Warren Buffett lays out a very rational argument for slightly higher taxes.

Our government’s goal should be to bring in revenues of 18.5 percent of G.D.P. and spend about 21 percent of G.D.P. — levels that have been attained over extended periods in the past and can clearly be reached again. As the math makes clear, this won’t stem our budget deficits; in fact, it will continue them. But assuming even conservative projections about inflation and economic growth, this ratio of revenue to spending will keep America’s debt stable in relation to the country’s economic output.
