Nobody is saying owners do literally no labor The OP literally says “doesn’t work”. Is “doesn’t work” not equivalent to “no labor”?

Owners do not work for a living, their incomes are not wages but a huge share of profit that comes from surplus value extraction. Doing some work here or there does not explain why their incomes are hundreds to thousands and even more times higher than workers, whose wages do vary but within a much more narrow band.
