There are many people who could have reversed these policies, but they were put into place by a generation conditioned by FDR and his massive federal takeover, and I think that made it unthinkable to do a wholesale reversal. Also, once the money starts flowing, everybody buys into it. Look at the black race pimps, look at all the “agencies” and NGOs that make money on the poverty industry.
Heck, Nixon (elected by boomers as a conservative) even extended the LBJ policies.
Yes, once money start flowing into the system there are entreched interests on both sides to keep the status quo in place, no matter how wrong it is.
So the boomers fiddled, while Rome burnt, and now they all cry in their beers and wonder who to blame.
