Demanding that the rich get a tax cut as a condition for tax relief for others is simply elitist.

Traditional economics is based on imaginary creatures sometimes referred to as 'Homo economicus.' I call them Econs for short. Econs are amazingly smart and are free of emotion, distraction or self-control problems. Think Mr. Spock from 'Star Trek.'

Claiming that Social Security benefits are safe may sound naive, but my view is actually quite cynical. I believe that as long as the elderly continue to vote in large numbers, no Congress will renege on promised payouts for those already eligible to receive benefits.

The more we turn down questionable offers like trip insurance and scrutinize 'one month' trials, the less incentive companies will have to use such schemes.

It's essential that we understand things like the free-rider problem, but we also need to understand that, fortunately, humans are a little nicer than economists give them credit for. Some people actually leave money at roadside fruit stands; some people give money to NPR so we can listen to it.
