Why should they welcome you in the house they use to LIVE in? As opposed a house they use to make money out of, without contributing anything to society, like landlords do?
Indeed, given how many people flat-out couldn’t afford to buy in a world without landlords, landlords prevent homelessness. Just like farmers, distributors and grocers prevent starvation.
Many renter commenters assume that anyone owning a house automatically owes the society to provide housing to those that don't. Of course such people don't actually like taking care of the house or pretend that depreciation and maintenance don't exist.
You should probably fix that also, no? Unless you want all housing to look like abandoned blocks in Detroit.
