This is why capitalism is successful. You need an honest feedback mechanism from labor. If a centralized government assigned people jobs of maintaining a shitty php monolith at a standard wage those people would effectively produce nothing, because it is a shitty job and those people would not enjoy it or work hard because it is unfair that other people get better jobs. The unintended consequence is income inequality but that inequality is the only way to get someone to be a garbage man instead of a youtube commentator or beer reviewer.
