Then why are you trying to call out “champagne socialists”? There are parts of the working class that have more than enough money to buy champagne and generally live a comfortable (or even affluent) lifestyle. There are even people who have made millions through labor alone, more rich than the petty-burgeoise. You’ve talked yourself into a contradiction.
I’ve also literally made the arguement that you are now making about working class not being how much you earn. I had to do this when someone tried to claim that programmers and police officers are not working class cause they earn too much. The difference is I don’t go around accusing people who work full time of being “champagne socialists” whatever that term means.
