10 Documentaries That Will Make You a Better Person

Wal-Mart: The High Cost of Low Price

The message: Shop responsibly.

Even if you didn’t shop at WalMart a hell of a lot (or ever) before Robert Greenwald’s 2005 documentary about the retail giant, we feel confident saying that those who did quit cold turkey after seeing the effects WalMart has on communities far and wide. The company’s superstores are the cockroaches of the retail world, spreading through neighborhoods like a disease. The doc takes a look at how WalMart exploits workers at home and internationally — thanks to its anti-union practices and sweatshop affiliations — and at its extermination of family businesses. Those low prices don’t come without suffering.
