I think the problem is not with renting but with letting owners hoard property (real estate or other) to profit from renting them out en masse, depriving others from ownership options. Also owners considering their property as something to do with as they want (exploit) rather than a duty of care. Best of both worlds for them: e.g. charge each month for software to pay for "ongoing development" and spend it on shareholders and/or features for growth but cut costs on support and maintenance... Or you know, rent out a moldy, drafty studio to a desperate intern who must move to Paris to work and doesn't have rich parents.

Maybe it proves your point that I'm technically a landlord now, but only to help out a neighbour so they could stay in the area for cheap, because they needed to downsize, approached me and we agreed on a very low price. I wasn't initially planning on renting it out because it needed some upfront work to be liveable, which might be even more selfish considering the housing shortage where i live...
