Trump is no more than a temporary obstacle to the established power. See how they have already removed him from power, how they have de-platformed him and vilified him and continue a legal witch-hunt even now, just to keep him off his game and thus unable to effectively plot any potential come-back.
Basically....
The problem is clear. Trump tried to win in a democratic contest. He tried to play the game. He played it with some unexpected moves, but he still played. And the game is
rigged. You can win a round against the house, but you can't win in the long run. They've spoiled it. They've bought the whole thing long ago.
To be sure, the upcoming economic crash will produce another populist in the mold of Trump. But that won't be more than another round, either. After that, he'll get kicked out, too. By any means, by all means.
@Cherico had it right the first time:
If the establishment has rigged the game, the only real solution is to adopt their self-made rules, which means: no rules. No holds barred, no trick too dirty, no play too ruthless. And that's the future. This won't be won by somehow outsmarting them at their own game. It's won by flipping over the board. Which is a sanitised metaphor to describe a far more bloody reality.
And you are right, too,
@Lord Greyscale : this process must be viewed in decades, not years. They'll be in charge for quite some time yet, and they won't leave until they're forcibly dragged out of the halls of power. Which
will happen, but not democratically and not peacefully.
When a man crosses the Potomac with a legion, whispering
alea iacta est -- then there will be a change. No sooner. And whether that change is really for the better.... again, I wouldn't say that with much confidence. My whole point is that democracy and the rule of law are already dead. Most people just don't quite know it yet. So the zombie republic staggers on for a while longer.
