Economists often like startling theorems, results which seem to run counter to conventional wisdom.
When you think of policies that are going to address inequality of wealth, you have to be very thoughtful about what economists call "incidence of taxes." If most of the savings is being done by capitalists, and you tax the return on capital, then they will have less to invest. That would mean, over the long run, that the rate of interest would go up. That would therefore undo some of the intent to lower the income of capitalists.
We could have saved Wall Street without putting our future in jeopardy. I predicted that there would be all-around consequences - in the long run as well as in the short run. People are now saying we can't afford health care reform because we spent all the money on the banks. So, in effect, we're saying that it's better that we give rich bankers a couple of trillion than giving ordinary Americans access to health care.
World War II was really unusual, because America was in the Great Depression before. So the war did help the US economy to get securely out of this decline. This time, the war [in Iraq] is bad for the economy in both the short and long run. We could have spent trillions in research or education instead. This would have led to future productivity increases.
The military is focusing only on the short run costs. If they don't provide appropriate body armor, they save some money today, but the healthcare cost is going to be the future for some other president down the line. I view that as both fiscally and morally irresponsible.
