Quantity of money per unit of output and price index is deeply intricate. At the end of the day, the more cryptocurrency is produced without needed and real usage in economy the lower the value of your crypto assets.
Since the year of 2000, people on average had to endure 2% inflation in USA. That means every year put up 2% on top of the thing you want. That means no matter what you had to become richer by 2%+ in order to not lose value in the things you own. Now houses of course made the most leap until 2008 but since than there has been a bit of drought, prices did dropped a bit and than went up again a bit but the volume has been issue.
Salaries didn't increase at all compared to 60+ years ago let alone 20 years ago, the salaries stayed around the same or just a bit more whereas inflation is increasing. Investments made huge leaps but than crashed at 2008 and than made another huge leap and crashed this year. Basically while inflation was going on, people didn't get richer to cover the difference.
Now the real problem is that Central Banks now belong to private banks, and new money doesn't get back in the market through increase of salaries but through loans that are provided to people who already have capital.
For employees, best way to have capital is through real estate, this kind of investment and wealth takes 30 years to build. More time, slower, less and less people that are employees can get rich.
