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.
