...the 2 largest tax cuts in the modern age (Reagan and Kennedy) resulted in INCREASES in government revenue.
And it can be simply turned around in your argument to say that the Democrat's response to these increases in government revenue was to add more unecessary government programs to spend all of the money (and more).
It is a simple thing to armchair quarterback government spending...but 2 graduate level econ classes with about 2000 pages of text barely scratch the surface.
Unfortunately for you...later in life you are probably going to hear over and over again about how the policies of REAGAN were responsible for the largest, longest period of economic growth in US history.
