The math has already been done. I'm not your high school teacher. Go look up, ex, housing co-ops for a relatively inoffensive example.

I'm not of the opinion that people with more than one house should be killed, but people who own a thousand? People who own houses they will never live in and have no intention of ever living in? Those people are parasites.

And you can talk about upkeep all you like but who's paying for they upkeep now? Not the landlords, that's for sure. Oh don't get me wrong, they're managing the upkeep and it's coming out of their account but all that money? The money is all coming from the tenants. The people living there are already paying the upkeep.

It's also an absolute joke to try to characterize landlords as being interested in maintaining property any more than is absolutely necessary when they're, as a class of person, categorically infamous for being cheap bastards who refuse to make any improvements or even do basic maintenance because it would cost them money. "Sure the heat may be out and the place may be drafty and the freezer may not freeze and the whole place may be infested with vermin but if we didn't keep paying the landlords for all this decadence the poor people would ruin it!"
