Under both Thatcher and Reagan, there was the escalation of the Cold War, income taxes was cut, privatization was pushed, tax rates for the rich were lowered, unions were broken, globalization over national interests were advanced, and military spending was massively increased.
I've been critical of Reagan. I probably haven't commented on Thatcher, because that's not where I live and vote.
Reagan's election was a reaction to the incompetence of Carter. He (Carter) was good on policy decision, but a failure at using the president's bully pulpit. In the 1976 presidential campaign, I was asking "Jimmy who?" I'm still asking. This was a terrible choice for candidate. We cannot blame everything on Reagan without looking to the failures that resulted in Reagan being elected.
I'm more distant from UK politics. As I saw it, Thatcher's election was a reaction to the excesses of the left (the Labor party). At least some of the blame should be assigned to Labor.
