As did Socialist Security. As did LBJ's Great Society, MediCare, War On Poverty. And virtually every other drain on America's economic system that we are dealing with today.
Perhaps what has changed is the definition of "Conservatism". What we know as Conservatism today didn't even really exist back then. It was William F. Buckley, Jr, William Rusher and a few others who brought forth the ideology we know as Conservatism today.
I know well the writing of Rusher, Buckley, Russell Kirk, James Burnham, de Toledano, Whittaker Chambers, Mel Bradford, Herb London. Read them all. Read National Review back when it was worth reading.
I am surprised to see that a scatological nitwit even knows Rusher’s name. Maybe some day you’ll even learn something about the political history of the 60s instead of spouting empty headed slogans. But more likely you won’t.
