A one-time massive pump of imaginary wealth. When people have imaginary wealth, they work like hell to increase it. Pumping a sudden shot of value into everyone's pocket would instantly stimulate the economy to do things of real worth - to make expensive things efficiently, for all the new millionaires to buy.

At the same time, completely scrap the current system of taxes - all of them, state local federal and sin. One tax for One People.

Rewrite the bottom line, change the mode of taxation.
