This is creating a ridiculous wealth disparity and deincentivizing a whole generation to get good with a skillset. I already heard from a lot of young people that working is not worth it, hard to disagree with them when even a basic thing like a piece of land or a house looks out of reach for a regular person.
But as you put it unsustainable things are not sustainable, society will regress until the equilibrium is found again. But things didn't need to be like this.
