Reaganomics was a shear failure. The budget ballooned, while housing crashes occured after Reagan's first supply side tax law. He blamed Congress for cutting too much, than later for cutting too little, then blamed the Volcker and the Fed for doing exactly what James Baker told them they should do. The GDP boom was mostly due to the Soviet Union's collapse.
Laisez faire was more phillosophical than a market practice. Sam Rayburn's anti-trust and populist economic legislation durring WWI and its subsequent success, 1929, and Lyndon Johnson and John F. Kennedy's economic booms all speak volumes for Keynesian economics and against laisez-faire. The invisible hand is invisible because it is not there.
