I don't think the economy is Trump's fault. He could do more to ease the pain, but pain is what we're in for. A massive unprecedented shift in demographics is underway, and everyone has been ignoring it. Trump has not really done much to help the problem, so it seems like we will end up being more reactive than proactive.
Unfortunately voters are probably even less proactive in their thinking than politicians. We saw that with Bush Sr. We can't get leaders who have real solutions unless they get voted into office.
