Nobody knows if Obama’s stimulus bill will help the economy. The politicians that say that this part or that part will or won’t work are full of it. Our government has to try stuff. Most of it probably won’t work; but some of it might. Then we have to try more stuff. A laissez-faire approach is worse than doing something that does not work.

Warren Buffett knows nobody knows:

Q: But there is debate about whether there should be fiscal stimulus, whether tax cuts work or not. There is all of this academic debate among economists. What do you think? Is that the right way to go with stimulus and tax cuts?

Warren Buffett: The answer is nobody knows. The economists don’t know. All you know is you throw everything at it and whether it’s more effective if you’re fighting a fire to be concentrating the water flow on this part or that part. You’re going to use every weapon you have in fighting it. And people, they do not know exactly what the effects are. Economists like to talk about it, but in the end they’ve been very, very wrong and most of them in recent years on this. We don’t know the perfect answers on it. What we do know is to stand by and do nothing is a terrible mistake or to follow Hoover-like policies would be a mistake and we don’t know how effective in the short run we don’t know how effective this will be and how quickly things will right themselves. We do know over time the American machine works wonderfully and it will work wonderfully again.
