Actually Social Democracy is more popular. Which is what I support.
Most of this is based on the basic psychology of motivation. Besides, our society is not emotionally advanced enough for full Socialism. It’s common for people to make personal relationships a matter of ownership. Think those people could manage to handle shared and equal partnerships with coworkers? Just reference the popularity of Real Housewives of the Trailer Park, gold teeth and the Kardashians. We’re a long way from Socialism.
