A lot of big tory brained comedy in that thread. Some choice quotes:
I’d be provided vital housing to those who want to rent. Not everyone wants to own.
The Landlord thinks they’re providing a vital service! 
People rarely remain in one income bracket over a lifetime, they gain experience and move up.
Rather telling of a sheltered life experience.
Well would you run a business at a loss? Would you work for nothing? (Charity aside)
Implying being a Landlord is work.
Forcing people to read Adam Smith would be a 1000% improvement over these dumbasses defending landlords.
Even the guy we (incorrectly) hail as the prophet of free markets knew that landlords exploited people when he wrote (very arguably) the first economics text.
