You are not even listening to a word I'm saying. Why SHOULD my friend (and his partner,) have saved every spare penny for a deposit to put down on a property? And then landed themselves with a crippling mortgage in their mid 40s, that would not have ended til they were 70?!
Why SHOULDN'T they have just carried on renting? Millions of people do it all over the UK, and all over the world, and no-one bats an eyelid, OR looks down on them. You claim you don't think you're a 'better person' because you are buying a home, but from the way you are speaking, you are acting like you think you're better. Quite a common attitude from some people who buy. Look down their nose at the renters.... 
You're literally acting like you know best, and everyone else is wrong. Not everyone wants to buy, and not everyone CAN. Many people can't buy a property for a number of different reasons!
As I said, my friends didn't want to buy, they were happy with the freedom and simplicity of renting, and yeah, the affordable rent. And they were reluctant to take on a big mortgage in their mid 40s. If YOU would have been happy to do that, then bully for you. Other people are not you.
My friend and his partner were entitled to have a nice life with a long term tenancy and affordable rent, just as many people in social housing are. They shouldn't have to buy because people like you say they should.
You clearly think this is all their own fault that they are now in their mid 60s, and are stuck in a high-rent, low security bedsit at almost £700 a month, with your smug and sanctimonious 'I told you so, nah nah nah nah nah' attitude. How charming you sound.
