I don’t think an Carter style excise tax makes sense but and excess profit tax targeted at oil companies who are profiteering at record levels at the expense of the greater US economy and at a time when the US government really needs the cash can be a good idea. This is a well known wartime fiscal instrument (put in place during nearly every other war in recent US history) and will unlikely affect the price of oil.
These funds could help the right fund their war in Iraq which will take trillions of dollars for many years to come. Even Reagan didn’t end the windfall tax put in place by Carter until the late 80s when things were stabile with Oil because of the need for the funds. Our government doesn’t have any money left to fund the war. Although if the tax does get put into place, I think it makes sound economic sense to take that money and invest in domestic businesses that produce clean renewable energy resources. This will directly benefit the American people, create jobs, and stimulate the economy while Iraq does none of those things. There are several economic examples of where this approach has worked.
And for those who say it’s not a few who prosper, I would argue otherwise. Take a look at the insider trading online. There are relatively few insiders who are caching in on millions and millions of dollars of these profits while the rest of us (probably 95%) who have some exxon in a mutual fund take a measly few bucks from that profit. The chairman takes almost a half a billion and you really want to cut the guy a break? These funds could be used for the greater good of the country in the face of a slipping economy.
