I can't believe that the free enterprise system is completely misunderstood, even on FR!
When you turn on that radio and "listen for free", it is because someone else is paying the bills (in this case, advertisers).
Now, reapeat after me:
THERE AIN'T NO SUCH THING AS FREE LUNCH"!!!!
Then read the Friedman's "FREE TO CHOOSE"- as good a place to start as any.
Huh? I'm forced to pay the advertisers? I never saw the bill in the mail....
