Yeah, when it comes to socialism, should be known that it isn't just wage leveling. Especially early on and without automation, some people will make more than others.
We're talking about a difference of the 1% owning about 15% of the wealth (as was the average during the Soviet Union's lifetime) vs. 1% to 60% (as is the case in contemporary Amerika). Doctors will likely make more than janitors for a long time.
Wage equalization is a protracted struggle, and a sign of the deterioration of the class structure as income disparity shrinks. It's a process.
It's a common accusation or hypothetical presented by anti-coms: why should a doctor who spent 8 years in school make more than an entry-level job? Well, we're not talking about immediate wage equalization. We're talking about workers setting their own wages collectively, and when workers control and plan the economy, we'll have a far more rational wage disparity. We already see this with profitable worker co-ops that can afford to charge ludicriously low prices for their services yet still afford to pay their employees well, oftentimes far better than bourgeois industries.
