Freidman makes some good points sometimes, but he loves to construct and demolish absurd strawmen.
Consider this little exchange (my transcription):
Ah, ideology. Friedman goes on to claim without evidence that OSHA (MSHA) does a bad job and we were just as safe 100 years ago as we are today. Which, of course, is demonstrably false.
Ashbrook: Let me ask you -- I mean, people struggle with this.

Friedman: Well look at those cases, those countries ... Russia had, uh, the Soviet Union had government-owned coal mines, and they had a very high rate of limbs coming off.
Ashbrook: [Pause] Okay, fair enough, and still ...
