Owning land is not a job. Trading stocks is not a job. These people are NEETS who have found a revenue stream.
In which part are you with OP? That UBI is a good thing or that rent isn't and landlords are leeches?
Whenever I'm dumbfounded by how people here conflate individual homeowners with corporate lanlords, I have to remind myself the average Lemming is probably 14 and doesn't understand the economics of renting. If you want to start somewhere, look up the 5% rule.
Blaming individual homeowners instead of corporate landlords is like blaming global warming on people who use plastic straws while billionaires take hundreds of flights in their private jets per year.
Just a reminder - the economy is an artificial construct invented by rich people to make themselves richer. There is no reason why it has to be the way it is (:
