Socialism & Fascism are two sides of the same totalitarian coin, with the latter ideology being an offshoot of the former.
While Socialism preaches the State being the sole owner of the means of production, Fascism preaches a partnership of State (Power) and Corporations (Money).
Socialism leads to rapid ruin, while Fascism leads to a longer and drawn out ruin. The destination is the same regardless of the speed in getting there.
Freedom and free markets are the only escape from this totalitarian vice.
