It took the great depression to drive substantive social/policy changes.... which ultimately led to 50+ years of prosperity....
Reagan and his mates brought in the policies that destroyed that, dismantled the systems / infrastructure that generated the prosperity... it has then taken another 40 years for the economy to "wind down", and for the policies instituted in the 1930's to 1950's to be wound down, sidelined, or eliminated.....
Sadly, I don't believe Trump alone is enough of a shock to the system, to drive the groundswell of support needed for the economic changes required to bring back true prosperity (and strengthen democracy).
The great depression led to an economic, political and social revolution... there are various forms of revolution, but one thing they almost always have in common, is how dire things have to get for the average "working man", before the masses get mobilised. The changes of the early 20th century were relatively bloodless .... other revolutions have not been so benign.
