And conscienceless freaks like Nixon, Reagan and now Trump will always find gullible, malicious and wounded people to support their bids for power and all of us, each and every one who isn't already rich and powerful, will always pay the price.  People aware of the coming disaster will protest, perhaps even shed blood and destroy property, as fates not of their making or to their benefit unfold.
We will always have young unless Trump flips out more than usual at some truth about himself he can't face.  We will always have stupid so Trump types will always find an audience eager for validation of their ignorant attitudes and their groundless opinions lacking all supporting fact.
This is the history of humanity as we strive for civilization.  No matter the spin put on it, no matter the scorn heaped on it people will react forcefully when old monsters convince fools to martyr themselves and take the rest of us up in flames with them.
