The pareto principle always applies. There will always be outliers. The only problem today is that many of the outliers are "cantillionaires" who got rich via political protections & fiat money creation rather than by creating value for others.
But what power does Saylor's Bitcoin give him over you & your life & your Bitcoin? If he cannot devalue the money you hold to enrich himself then he isn't harming you. If I build 1000 houses and rent them to people, why would people rent them from me unless they prefer my houses above all other options? Why didn't they build their own?
In a healthy free market the amount of value that belongs to someone else has nothing to do with you. People do not get rich at the expense of others, they only get rich to the benefit of others. If I earn 1000 Bitcoin then I have created far more than 1000 Bitcoin worth of value in the lives of other people. And it was those people who decided for themselves that what I had to sell would improve their life more than the money they voluntarily parted with to aquire my goods or services. If each individual isn't able to decide for themselves what makes their own lives better, then who is? There is no fairer way of determining the merit of a person's contribution to society than by free trade & sound money.
