Owning your own home is absolutely a luxury that should only be afforded by a given percentage of society.
I never said anything about owning, I said housing was a basic human need, be that owned or rented. Allowing the wealthy to buy up swathes of property to make a profit on at the expense of those less well off is exploitative. I'm not arguing against a rental market, I'm arguing for a better regulated rental market. The same way other basic needs, like food, utilities, fuel, and medicine are regulated. Do we really want to see a system where people have to choose between rent and food or heating?
If you make a luxury like that available to everyone, then what incentive is there to better oneself, seek out and take advantage of opportunities etc?
Removing incentives to succeed has a hugely detrimental effect on society.
Firstly, defining success by how wealthy you are, or how many assets you have is one of many problems with our society.
Secondly, I'm not sure making it so the single parent has to work 60 hours a week, or the family of 4 have to choose between food and rent, just to keep a roof over their heads is the most effective way to encourage people to "better themselves".
Thirdly, it's a complete and utter myth that anyone can "succeed", if they want to. For society to function you need a foundation of manual/low skilled (hate that term) workers to bear the weight of those above. If every cleaner/carer/refuse collector (not that I'd deem these to be low skilled but our society does) were to decide, and were able to become, engineers/doctors/architects society would collapse.
Why would you want to create/support a society where those at the foundation are expected to live in shit conditions, worrying about how they'll make rent next month or be able to afford their kids Christmas presents, while those at the top have more than they'll ever need in a 1000 lifetimes?
In my opinion we should be striving to reduce the gap between the foundation and the top of society as much as possible. One way to do that is to ensure that everyone, regardless of their wealth or status, is be able to have a safe, secure, and affordable place to call home. Removing that stress from people's lives would undoubtedly do more to encourage and allow people to "better themselves" as they'd more energy and money to do so.
To answer your question, yes I think the government needs to back right out of people’s lives and leave the invisible hand to do the work in the vast majority of cases.
I do agree that there are some examples of market failure (such as environmental matters) where the government should step in, but the housing market is not one of them.
Can you not see the contradiction between those two statements?
You're happy for the government to step in on environmental matters because you know companies/individuals cannot be trusted to regulated themselves. I'm also guessing your happy for the government to regulate other necessities, like fuel and food, to stop companies exploiting them, or would you prefer to let companies raise the price of food until the poor can only afford bread and water to eat?
Why is housing different?
