In SOCIALISM, there is no private property. The Sovereign owns all property, all factories, all farms, all hospitals, all schools and universities, all residential housing, etc. The individual owns NOTHING, except his clothing, trinkets, and other personal property.
Democrats, I suspect, long for the delusion they have of Swedish or Danish, or Norwegian "socialism" where everyone is prosperous, and the Government protects everyone from birth to death with "free" healthcare, guaranteed minimum wages, generous pensions, free education through university, and so on.
If you want an interesting discussion, try telling a Swede that his country is "socialist," then stand back, while he spends the next half hour telling you what a nitwit you are for believing that.
But I have no doubt that THAT is what Democrats see when they are asked if they favor "socialism." With all due respect, it is the choice for losers, which is why it is so dear to Democrats.
