You really need to learn more details. Soviet Union was already in a decline with central planning, and communist methodology. Star wars was just a very small portion of spending. I was directly involved in working on a star wars project so I have a fairly good idea of money spent. Majority of spending bills signed by Reagan were for social services and welfare. That was exactly what the majority democrat congress wanted.
Opinions are not a good substitute for facts and figures. As for Reagan’s tax cuts, he deserves huge credit. My own personal tax bracket dropped from 43% to 28%.
