I think the powerful are growing more insecure, intolerant and frightened with each generation.
Eisenhower ruled, JFK tried to.
What was Trump going to do to them? Tweet?
(Its not only the masses who have degenerated...)

I'd argue it goes back alot further than that, Eisenhower was theirs.
It has always had the power to work for them, against them is a different story.
Eisenhower was a domineering and difficult man, with no private vices, and the Presidency was far from his first rodeo. He said "no" even to elites, often and harshly, even though he was philosophically on their team. Mostly... His MIC speech was a peek behind part of the curtain.
There hasn't been a remake of that movie. He wouldn't rise beyond Lt. Col. today.
Kind of shows you how useless the position is though, the best that could be done was to give a brief warning...
If you read "Confessions of a Nuclear War Planner", among other books, Eisenhower did manage to slow the progression of the disease while in office, thus allowing an economic boom, infrastructure development, and real wage increases. And he avoided being corralled into global nuclear war more than once.
But yes, his warning was his only lasting achievement.
