It's good that Randi and occasional TV reporters expose the sellers of such "magic." But after I did that for 25 years, I concluded that the harm done by those hucksters is minor compared to the scams perpetuated by politicians.
They promise fiscal responsibility. Then they spend like drunken sailors.
They promise to cure poverty. Then their programs make it worse.
They promise to create jobs. But then they make life so complex and unpredictable that entrepreneurs are afraid to create jobs.
Almost none of their promises come true. But few people approach government with the skepticism it deserves.
Whether you believe in God -- or psychics, or global warming -- that's your business. I may think you're stupid, but if you waste your money on, say, a "strength" bracelet, you only harm yourself.
But being gullible about government hurts everyone. Government is force. When it sells us bunk, we have to pay even if we don't believe in or want it. If we don't pay up, men with guns will make sure we do.
It's good to be skeptical. It's really good to be skeptical about government.
