That's not correct.
First: even in conditions of equal opportunities, outcomes almost always include a percentage of randomness.
Practically all developed societies understand that and employ forms of progressive taxation and wealth redistribution. This is widely supported by economists except few fringe libertarian extremists.
Second: difference in outcomes are seen as justified only within reasonable ranges.
Polls show that people find acceptable for top performers across various jobs to earn 2x, 3x, 10x the average income. Not 10000x.
