Well, we'd reintroduce massive tax loopholes that allow for real tax rates to be less than they currently are - that's how we'd get back to that, because that's what we had then. We'd also cut payroll taxes back to 3% and have them apply to the first 30,000 instead of over 6% and applying to the first 106k of income.

We'd also raise taxes on the poorest quintile - you know, the people that currently don't pay any, and repeal medicare taxes.

That'd pretty much get us back to post ww2 taxes.
