Require? Genuinely require? It seems to me the high cost comes from attempting to create profit margin. If the profit is basically eliminated, the person can have the high wage, and we can have the nice things.
You can set up marxist organizations in a free country. They're perfectly legal. They just cannot force people to join, or prevent people from leaving.
A lot of nice things in life require that someone make a low wage so they are affordable to you.
