How can an economic crisis cause citizens to accept a totalitarian government? Jobless citizens become desperate for someone who promises to solve their problems. Jobless citizens want the government to provide handouts to feed and clothe them. Citizens tire of seeing undeserving citizens thrive while they continue to be desperate. Citizens want for themselves the kind of power that comes with being a totalitarian leader.
"Jobless citizens become desperate for someone who promises to solve their problems" would be the best option, since this is what transpired in many of the fascist countries in Europe between WWI and II.
