It is pretty simple, imo. the way of life many outside the big cities used to live is dying off. Neither party has a plan for that, because it requires, you know, admitting the world is changing and complex changes need to happen. Instead of voting for real change, they voted, imo, for the party that promised to go backward in time to a 1950s that never really existed. I don't think it is much more complex than this. A yearning for avoiding loss, a loss that is inevitable, frankly. And a party willing to lie to get power, and another party with no plan at all (and is also full of liars). The irony is that it was Reagan and his revolution that removed all our unions and others that actually protected workers from having any power, and we just put his party (even more backward looking) in virtual full control of the federal government and 2/3 of the state governments.
