That's true, but tax cuts didn't kick off the one under Clinton. Since as we are constantly being reminded, he raised taxes and the economy did well.
Income inequality began its rise in the 1970's and increased under Reagan, and of course we see where we are now. Which is personally, what I would rather talk about, because all of this other stuff is nonsense to me, but, trying to claim that Reagan is responsible for anything good that happened after his presidency is just right wing hogwash. And they always skip right over the bush I years, where the guy, saddled with a recession and a crushing deficit, had to raise taxes to be responsible, and frankly to clean up Reagan's mess. And promptly got voted out of office largely because of that.
It must kill some that a dem didn't win that election. Oh, how much easier their revisionist history would be written then.
