Do you own any stock in any company?
Or a Mutual fund that owns stock in any company?
Then you pay tax at 35% on that companies earnings + whatever your marginal tax rate is...
That was my only point... Warren's personal tax rate might be artificially low, but he neglects to mention that most of his taxable income has already been taxed at least once at the corporate level.
I'd agree that his personal tax rate should be higher IF and ONLY IF the tax on Corporations were recended.
