Rasmussen says 46% already favor government guaranteed jobs.
Hillary admits 41% of Democrats already are socialists.
All it will take for socialism to finally succeed is the onset of the depression the Feds keep intervening to prevent. One can intervene only so many times after which that doesn't work anymore. The problem is the interventions distort the course of capitalism so much that its natural mean-reverting ways will have to be by definition quite severe next time. Enter outright socialism because the young have been brainwashed against capitalism and will clamor for something other than capitalism or the Fed interventionism (aka state capitalism) which hasn't worked.
There will be blood.
