The price of a piece of clothing is not at all indicative of the working conditions of its manufacturer. On top of that, implying (or outright saying) that there is something morally wrong with paying ten dollars for a t-shirt is incredibly classist. The truth is that when brand names charge higher prices for their items, that extra cash usually goes to two places: into the pockets of CEOs and other higher-ups, and into the company's advertising budget.
