The Reagan "Tax Cut" was only for the rich. While all the rates went down Reagan eliminated most of the write offs that working families could use and he even raised the threshold for deducting medical expenses up to 6 or 7% of income. So most working class families ended up paying more even though the rate was cut slightly. The rich got massive tax cuts that more than made up for the loss of tax deductions.Considering that tax rates are going to jump up to where they were in the Reagan years (which was actually a cut from where they were in the Carter years), you're a fool if you really believe all the campaign promise rhetoric.
The loss of these write offs really hit working families hard, and are especially burdensome now when credit card debt loads carried by working class families are at an all time high.
