You forgot 1) fica taxes, including the 2.9% bit that goes on forever, and 2) the phase out of itemized deductions. Anyway, after opening up my 2008 return on turbo tax, I see that I paid 31% of my adjusted gross income in federal taxes, so if you triple that, the total take would be 93% of AGI. For 2009 the percentage will be higher.
Well, 93% would be a pleasing top rate, but certainly not reasonable as an overall percentage.
Its funny you pay such high rates though - you must have an truly enormous income. As and old lady I used to know used to say when we talked about capital gains tax rates - 'you should be so lucky'.
