No one earns more than their labour could possibly produce. That labour however does have greater or lesser value to society, hence different pay rates.

My example above show that it's impossible for any one human to earn that much even if they were immortal and had lived since Homo Sapien migrated out of Africa.

That we have billionaires shows that a very large amount of people have been paid far far less than their labour was worth.

That value extraction goes away when ~~labour owns the means of production~~ the employees own the company (i.e. employees are the shareholders and reap the dividends).
