Economic inequality inspired Occupy Wall Street, a movement that in a few short months transformed our political with the concept of the "1 percent" and the "99 percent." Today the presidential candidacy of Bernie Sanders is altering the political landscape with a call to reduce inequality.
Why does this theme resonate with so many voters? How does it intersect with other issues like social justice, national security and the environment? Is inequality irreversible?
We are living through the greatest "wealth grab" in history. But inequality is not produced by immutable forces. It's the result of a legislative agenda promoted by the rich and executed by their political allies. The struggle to change this agenda and end inequality is inseparable from the other critical struggles of our time.
What follows are 10 facts about the 1 percent -- but they're not just statistics. They're a paint-by-numbers picture of an economy, and a democracy, in urgent need of change.
1. Not so long ago, growth and prosperity were more widely shared in this country.
There was a time in living memory when the growth in American productivity was shared much more broadly than it is today.
As economist John Schmitt wrote in 2013, "From the end of World War II through 1968, the wages for workers in the middle, and even the minimum wage, tracked productivity closely."
This led to the growth of a middle class whose members could meet their own needs, afford some luxuries, and raise and educate their children -- often on a single working person's income.
While many people, especially people of color, were shamefully excluded from this prosperity, the postwar American experience shows us that it is possible to promote broadly shared economic growth.
2. Then something changed.
But then, as Schmitt observes, something changed. Increases in prosperity were no longer being shared in the same way. He writes:
"Between 1979 and 2012, after accounting for inflation, the productivity of the average American worker increased about 85 percent. Over the same period, the inflation-adjusted wage of the median worker rose only about 6 percent, and the value of the minimum wage fell 21 percent. As a country, we got richer, but workers in the middle saw little of the gains, and workers at the bottom actually fell behind."
If the national minimum wage had kept pace with productivity, says Schmitt, it would have been $22 per hour by 2013.
Instead it's $7.25 today.
A slightly more conservative calculation from economist Dean Baker said the minimum wage would have been $18.42 per hour in 2015 had it kept pace with productivity. This graph illustrates the broadening of this gap:
3. Most of the nation's income gains are now going to the top.
On the other end of the spectrum, income gains for the top 1 percent now dwarf those of other households. In 2011 the Congressional Budget Office (CBO) found that "between 1979 and 2007, income grew by: 275 percent for the top 1 percent of households; 65 percent for the next 19 percent; just under 40 percent for the next 60 percent; and 18 percent for the bottom 20 percent."
And most of the gains since the 2008 economic crisis have gone to the wealthiest among us.
Meanwhile, in what is sometimes called "the middle class squeeze," the middle-class cost of living has risen significantly. Even after wages are adjusted for inflation, middle class income has failed keep up with increases in costs such as child care, higher education, health services, retirement, and housing -- expenses that disproportionately affect middle class households.
4. Wealth inequality has returned to levels not seen since the "Roaring Twenties."
Economists Emanuel Saez and Gabriel Zucman found in 2014 that the concentration of wealth held by the top 0.1 percent has reached levels not seen since the 1920s:

Saez and Zucman found that in recent years there has been, as the caption to one chart puts it, "a surge in top wealth shares concentrated in (the) top 0.1 percent."
5. The 0.01 percent -- a tiny group of people -- controls a vast amount of wealth.
As a result of this surge, 16,000 Americans hold as much wealth as 80 percent of the nation's population -- some 256,000,000 people -and as much as 75 percent of the entire world's population.
The combined wealth of these 16,000 people is more than $9 trillion.
6. 536 people, $2.6 trillion dollars
A few billionaires are even wealthier. In the United States, 536 people had a shared net worth of $2.6 trillion at the end of 2015. These days even the top 0.01 percent isn't immune from inequality.
"7. CEOs are taking up a bigger piece of the pie, and workers are getting less.
Fortune 500 CEOs earned about 42 times as much on average as the typical worker in 1980. Today they earn 373 times as much.
In fact, seven of this country's 30 largest corporations paid their CEOs more than they paid in taxes.
8. The average American household is falling behind on wages.
The median household income in the United States fell by more than 7 percent between 1999 and 2014. It's now slightly over $53,000.
9. The average American owns less wealth than people in many other developed countries.
The median wealth of an American adult is roughly $34,316.
That's far below that of adults in countries like Japan ($78,862), Luxembourg ($78,453), the United Kingdom ($75,734), Norway ($54,362), the Netherlands ($52,649), Switzerland ($43,700), and Australia ($47,477.)
10. More than one child in five lives in poverty.
The US poverty rate for children is over 20 percent, higher than that of all other major developed countries. The only other nations in the OECD with similarly high rates are Chile, Israel, Mexico, Spain, and Turkey.
By contrast, child poverty is less than 9 percent in the Nordic countries and Austria, and is less than ten percent in the United Kingdom. Even those rates, which are less than half the American rates, should be considered unacceptable.
Overall, more than 48 million Americans live in poverty.
According to experts like Nobel Prize-winning economist Joseph Stiglitz, the expansion of the financial sector has contributed significantly to the current crisis. So has the lack of jobs and growth in minority communities; lax federal oversight of banks and corporations; the stock market's focus on short-term gains over long-term growth; the waning influence of labor unions; the offshoring of American jobs; and tax policies which have increasingly favored corporations and ultra-wealthy individuals.
Political choices are shaping a new class of super-wealthy Americans. And, conversely, the super-wealthy are shaping our political choices. A Princeton study by political scientists Martin Gilens and Benjamin Page concluded that "economic elites and organized groups representing business interests have substantial independent impacts on U.S. government policy, while mass-based interest groups and average citizens have little or no independent influence."
A government controlled by wealthy individuals and large corporations will be much more likely to harm the environment and subvert democratic processes. It will cater to the defense industry abroad and the for-profit prison industry at home. It will hamper racial justice, because true equality cannot be achieved without effort and cost. Its policies are likely to foster growing instability at home and abroad, affecting virtually every aspect of foreign and domestic policy.
That is why runaway inequality is the central issue of our time. It stifles democracy and leads to a more dangerous world. We should, of course, demand that political candidates advocate the right social, foreign policy, and environmental decisions. But even the best candidates will find it impossible to consistently carry out the best policies in a society where so few have so much and so many have so little.
Here's the good news: Today's inequality was created by choice, which means we can make different choices. We can end the great wealth grab -- by strengthening collective bargaining rights, regulating Wall Street and large corporations, fixing our tax system, and renegotiating bad deals like NAFTA while blocking such deals in the future. Ending the great wealth grab will improve life for most Americans, and will make it easier to reclaim our democracy.
It can be done. To say otherwise is to encourage a false cynicism that breeds permanent despair. It's true that it will take a major political shift, the kind of mass movement Bernie Sanders calls a "political revolution." But it can be done, once we understand and accept the challenge that lies before us.
