6. 55 minus 10

Below is an image of the US Federal income tax rates for 1955 adjusted for inflation.

Lop 10% off the rate in each bracket: 20% becomes 10%, 22% becomes 12%, all the way up.

The biggest reason for directly basing it off the 50s tax rates (and lower than what was in effect then) is to fire a shot across the bow of everyone these days throwing around the term "socialist" for policies that used to be considered "right wing".
