When I try to find somewhere to live, complete failure means homelessness.

Only if there are zero other rentals on the market, which is never the case.

When I try to find someone to rent my property, complete failure means I lose an investment property

Only if you are not a small time landlord. Big landlords can afford to lose income. Someone with 2 -5 properties cannot. That’s up to 50% of their income for the year. And not only that, a complete job loss if they lose the property, risking homelessness. It’s still a job for small landlords.

This is once again a battle against billionaires, not your local neighbors. Stop acting like specific jobs are evil. It’s the amount of money a human sucks up that is evil, not the job they do (well to an extent of course).
