The issue is the profitable part. The landlord purchases and rents a property because it’s profitable. So presumably, with enough starting capital, the tenants could be living there, with their own mortgage, for less. In addition, their mortgage payment would be going towards equity rather than funneling to a landlord. The distaste for landlords exists because for many rental situations, it is literally someone with money, leveraging their money against someone with less money. People don’t have the option to not live anywhere, so they are forced into extractive contracts.
The Romans built off of Greek culture, Europe built off of Roman culture, the US built off of European culture. US math is very much based on Greek math (and US education in general). You may remember doing Greek proofs in school. Greek math was by no means superior to any other culture's, it just so happens that US culture descends from Greek culture.
