Arthur Laffer on making a bad situation worse:
When markets are free, asset values are supposed to go up and down, and competition opens up opportunities for profits and losses. Profits and stock appreciation are not rights, but rewards for insight mixed with a willingness to take risk. People who buy homes and the banks who give them mortgages are no different, in principle, than investors in the stock market, commodity speculators or shop owners. Good decisions should be rewarded and bad decisions should be punished. The market does just that with its profits and losses.

But here's the rub. Now enter the government and the prospects of a kinder and gentler economy. To alleviate the obvious hardships to both homeowners and banks, the government commits to buy mortgages and inject capital into banks, which on the face of it seems like a very nice thing to do. But unfortunately in this world there is no tooth fairy. And the government doesn't create anything; it just redistributes. Whenever the government bails someone out of trouble, they always put someone into trouble, plus of course a toll for the troll. Every $100 billion in bailout requires at least $130 billion in taxes, where the $30 billion extra is the cost of getting government involved.
If you don't believe me, just watch how Congress and Barney Frank run the banks. If you thought they did a bad job running the post office, Amtrak, Fannie Mae, Freddie Mac and the military, just wait till you see what they'll do with Wall Street.
His point is that there are always winners and losers. All the government will be doing -- in addition to doing all the damage it can -- is choosing different winners and losers. "Panic" does not usually result in rational action.
