I love this sentence:

To my mind, the real scandal is not that a large corporation doesn’t pay people more. The scandal is that so many people have so little economic value. Despite (or because of) a free public school system, millions of teenagers enter the work force without marketable skills. So why would anyone expect them to be well paid?

The root cause!  Why would anybody be interested in that?  It’s easier to make excuses, that’s why.

Here’s the conclusion of the undercover Wal-Mart guy.
