A bad economy and runaway inflation created Hitler. (I have a postage stamp for 3 billion marks), and caused him to purge millions of Jews, and caused WWII.
A bad economy caused Stalin to purge millions of Kulaks.
Mao Tse Tung killed millions in China because of the bad economy.
Read your own words. "A bad economy caused Stalin to purge millions of Kulaks."
That is an indefensible historical LIE.
