The article from your first link says this:

"Reaganomics is based on the theory of supply-side economics. It states that corporate tax cuts are the best way to grow the economy" 

Ummm ...No it doesn't 

"Reaganomics" aka "Supply side" is the idea that we might want to look at the taxation and regulation, the structure, of the supply side of the economy and see if we can make it work a little better. Cuts in the marginal tax rates for corporations is such a very small piece of that its hardly worth mentioning. Thats where I stopped reading 

Just so you know ... Reaganomics didn't presume or assume that all tax cuts increase tax revenues. Even the Laffer Curve--a mathematical certainty when properly stated--only says that sometimes tax rates can be so high that this will be true. We even have real world evidence that certain taxes at certain rates actually lose revenue as those rates are too high. 

Reagans tax cuts paid for themselves
