Like many I have taken to using the word “socialism” to describe the politics of state control. It goes under a variety of names, for its different versions- “communism”, “liberalism”, and “progressivism” among others- but “socialism” has seemed to encompass them all and capture the emphasis that such people put on the group over the individual.
It’s a very deceptive word however, which is why of course socialists use it. “Social” is a word that has usually very warm connotation. A person with a good social life has enjoyable relations with a variety of people, including probably having sex with them. Sounds great! A social or sociable person is someone you would enjoy being around. A social event will probably be fun and enjoyable.
But all of these things have to do with one’s voluntary relations with others and nothing at all to do with the government controlling, preventing or compelling anyone. Socialism sounds like a big party, kind of like a potluck where people bring and share what they have and have a wonderful time. In reality people under socialism are completely atomized, there are only themselves and the state. The state takes what it wants, gives what it will, and orders as it sees fit. The choice of the individual is completely drowned out, with only microscopic influence in the occasional election.
Libertarians like to use the term “statist” and this exact same rant has been written by many libertarians before. And yet that isn’t very helpful either, since almost everybody believes in a strong state, only disagreeing on what it should do.
Leftism seems to be the only reasonable term. It only describes a seating position in the old French legislature but since those days everyone knows what leftists have stood for, more or less.
