I pay an electrician a slight premium for knowledge and experience that won’t burn my house down. Sure, I could look it up on YouTube but the probability that I do something wrong probably outweighs the premium I would pay for a qualified electrician.
Communism advocates for the workers owning their own means of production. An electrician working as a sole trader is an example of this. It is perfectly consistent with anti-capitalist thought to hire someone to perform work.
It’s completely fair and it’s also not quite what people who critique capitalism are talking about. Imagine you’re hiring a company that has electricians on payroll, then by definition the electrician you hired will get less than the labor he performed, and the company will pocket the difference as profit - or it won’t stay in business long. Electricians have the option of going alone, many other industries not so much.
Another profession where freelance is a common option is coding. So if going alone should always better, is the implication that all the employed electricians and coders are irrational or want to be exploited?
There are clearly advantages when working for someone else. Is the negotiation between the employee and the employer always fair when an industry has a few established incumbents? That depends and there’s a large spectrum of possibilities.
How is this unfair?
