FYI Of the 10 worst stock market crashes in the 20th century fully 1/2 took place under FDR, the New Deal, and presumedly (Judge) Douglas. To wit:
#1) 4/17/30 - 7/8/31
294.07->41.22 -88%
#2) 3/10/37 - 3/31/38
194.40->98.95 -49.1%
#4) 9/31/29 - 11/13/29
381.17->198.69 -47.9%
#8) 9/12/39 - 4/28/42
155.92->92.92 -40.4%
#10) 9/7/32 - 2/27/33
79.93->50.16 37.2%
The winds of time are continually shearing away the gilt of FDR's legacy.
Actually, 3 of those 5 crashes you listed above (#1,4, and 10) occurred under Republican President Herbert Hoover.
FDR was awful, also, of course. Generally speaking, both Democrat and Republican Presidents are awful. There are few good Presidents; America is a great country in spite of the Democrat and Republican Parties, not because of them.
