I know all of us just want to make our fellow humans to make them rich, but don't you ever think if all of us are rich then who would want to work for us? And everyone will be lazy. Do you really want all of the people to get rich? Except if humans finally builds a complete operational AI Robot that could do all the work for us.
It's not likely to happen that all of the people will become rich, there's a balance that is set to this world so there will be rich, middle class and poor. Actually the rich people aren't lazy at all, they are even the most hardworking people in the world. Watch the story on how these rich people waking up early in the morning as they value time. I want to get rich and if you consider that everyone should aim for it too, there's no problem at all. But we don't have the same type of motivation so what you are worrying is absurd.
This is what will happen in some of people that become rich from crypto, are becoming lazy and the workers will also be reduced.
And I was thinking about that if all people in the world are become rich by crypto, I think not all.
