Deregulation under Reagan was a huge boost to Free Enterprise. Look at the airlines, and above all, look at the demise of Ma Bell. What was it other than a state supported monopoly? A very fine example of one, to be sure, but a state supported monopoly, nevertheless.
What you say is true. And there were other small battles won along the way - Michael Milken put many current companies on the map - we would have never heard of Ted Turner (unless you were a sailboat enthusiast) or Ross Perot, and many others without Milken.
But there was no dismantling of the true Socialist programs that are intact to this day. And yeah, there were a few things that Reagan was able to accomplish but he promised to do away with the Dept. of Energy and Education and actually ended up expanding the DoEd. with Terrill Bell whose first job was supposed to be to dissolve it.
Ronaldus Magnus did away with more Socialism in _other_ countries than this one. ;-) ... unfortunately. Having a Dem congress didn’t help. Imagine Reagan with the ‘94 congress - although as I stated they had their share of RINOs as well.
