Socialists and Commies get annoyed at this because they always overestimate the value of their own labour.
Afterall, they have PhD’s in gender studies, they should be making the same as a PhD in Neuroscience or Aeronautical Engineering!
They completely ignore the market for their worthless skillsets and simultaneously devalue the market for the others.
The same logic is why they misunderstand how destructive minimum wage laws are. The market decides value - I’m not hiring someone at minimum wage for basic work that needs to be done, I’ll just bundle it in to my regulated min wage employees jobs instead of hiring someone who could do it cheaper and gain skills in the process.
1 unit of labour =/= 1 unit of someone else’s labour. This should be fucking obvious to anyone with a brain.
