What needs redistribution incentive is assets not income. Anyone can get income, even disability is income. However assets are increasingly out of reach.
If you redistribute passive income, you redistribute access to assets. If you redistribute assets, you redistribute access to passive income. They are one and the same.
Also, an investor risks to lose the investment when the market crashes. Not everyone thinks about that during a market rally though; during these it looks like you can keep making tons of money for a long time.
I'd say that investing in a car repair shop and the appropriate skills would likely pay more, that is, would produce more assets faster.
