In my opinion people should only be able to earn money through work. After all, if everyone stopped working and started living off their investments, there wouldn't be any capital gains.
The problem isn't that capital is lazy, it's that the interest rate can't actually reach 0% and the capital market can't actually reach an equilibrium so it is stuck at some low interest rate floor instead of going all the way to 0%.
The idea that your net worth should grow based on how much you own is absurd. You should instead be paid more for your work and then get to increase your net worth that way. That's better for everyone involved except for those who don't want to work at all.
