Landlords don't even do that once they own an entire apartment block or all the land in a neighborhood. They obviously hire management and maintenance to do all the work for them. Or they form an LLC underneath themselves to do everything. The only landlords I've ever seen who did maintenance directly owned maybe two or three properties and worked because they couldn't afford not too.

I think a lot of liberals can only conceive of small independent businesses. Just endless expanses of independent bakeries, family owned tailors, and used car lots. Once it gets to the level of abstraction of capitalists owning companies that own companies that manage other companies, their brains get fried and it becomes harder to justify I guess.

So they just don't think about it.
