The blog of Reason Magazine had an entry about health care called : Our Craptacular Health Care System (And Why We Deserve It). It's not really the entry itself that's interesting, but rather the comments. Lots of smart people there (but what do you expect from a libertarian blog ? ;).
Below the Beltway speaks up for Wal-Mart :
I will be the first to admit that I'm not a fan of Wal-Mart. I don't enjoy shopping there, and the products they sell don't appeal to me. For a large segment of America, however, Sam Walton's creation has opened up opportunities that didn't exist before. To argue that you care about the working poor at the same time you attack the one institution that has helped them the most in the past 20 years is the height of hypocrisy.
