Where did you get that from? The wealthiest 1% of Americans alone pay 50% of the federal income tax. The bottom 80% pay only 15%.

Edit: at a 50% marginal tax rate if the 1% get 60% richer through this kind of automation and offshoring, we could lower the tax rate on the bottom 80% to zero!

Edit #2: If the 1% get 120% richer, we could start handing out checks to everyone in the bottom 80% equal to what they're paying in taxes today! See where I'm going with this?
