The Tax Foundation has published an article entitled, "Can Income Tax Hikes Close the Deficit." Here is a nice snippet: See article for Table 1. I should also add, this is for the tax year 2010. The rate would be lower in forthcoming years as the deficit is expected to be lower, nonetheless, substantial increases would be needed; the article provides more information as to what The Tax Foundation thinks those rates would need to be. Interesting article. It suggests we need tax increases combined with large spending cuts in order to eliminate the deficit or a major overhaul of the tax code to generate an obscene increase in revenue; neither seems very likely to happen. Makes me think about whether or not this is the country I want to attempt to accumulate wealth throughout my career in.
