Owning capital isn't either, and yet it's the cornerstone of the rigged casino we call our economy.
You pay way more tax on the money you labor for than the money you win through gambling on Wall Street, and while you may win or lose, the owners can and do effect the outcomes to ensure they win.
Oh and just to be clear, the winners are not the workers or the society, but private shareholders, and almost certainly not you to any significant degree.
Maintaining the structure is a job, sure, but most landlords don't do that, they just pay others to do it out of the money they leeched from tenants. Being a middle man leech isn't a job either.
Well I have a few rich friends and they said it's incredibly profitable and you don't actually have to do anything since you can just hire someone that does it for you. It also barely needs maintenance since the people living there are responsible for cleaning their house.
That's not what Alakazam is talking about here though. Just by owning land, it generates money, magically, from "nothing". And then the vast majority of landowners use that as excuse to entrench their wealth and then you get... Waves hands at hyperinflated rent crisis what we're all stuck in now.
Whether someone wants to be one of the "good land owners" or not doesn't change the fact that the system is set up for the ones that want to exploit it
I'd say renting out property you own is not a job, owning land and keeping it nice and clean or dare I say it growing some vegetables is very much a job.
