Nobody will pay you unless you are creating surplus value to them. If you have the means to sell your own thing, you are the one enjoying this value.
You might as well spend more hours running your own business. The way I see it is that it is mostly mind-numbing. Between the extra hours in commute, the fatigue, and the eventual drop in productivity, the biggest damage is to your own intellect, creativity and health.
Arguably you could be better off if you invest this time and energy to yourself. But this is still not fair. If you don't have the resources, then you can only make a living by selling your own energy to somebody else. And your business might also fail, so you go bankrupt.
I really believe the solution to all this is unions. All the high-paying jobs have some union protection set up, hence they enjoy living wages and perks. It is only plain workers that haven't any.
