Massive rents are not the norm though, and even low rents are capped by bedroom tax. And massive rents arose because of competition- something that could be prevented by building social housing.
Also: I live in a cheap area. We are cheap for a reason, low employment. Why do people think our area can absorb all the people considered too expensive to house in London? We already have silly competition for jobs, massive housing waiting lists of our own (poor area = low rent but also low incomes so more housing need), all the extra demands on health and social services that poverty brings. All a large influx of people would do to our area is cause extreme deprivation and make it harder for the people working here to cope with housing, health,, school places etc and the needy here to turn their lives around. What special right does the SE have to being naice that it thinks it is OK to do this to us? instead of us having to lose our places on waiting lists for newcomers and the like, why can't the SE build social housing?
I am not in the Welsh Valleys but not far either, do people really think that areas like that need a big influx of deprived people? That they can cope? Why do people think those areas ARE less expensive anyway? Because wages are lower and jobs more scarce. Meaning there is already plenty of competition for often scant resources.
I don't think people should be entitled to expensive prime estate of course, but I do think LAs should have a responsibility to support their own people or areas like mine become a ghetto, a dumping ground. We work, but don't earn masses- why is it OK to use our taxes to support people but SE residents don't want their council tax used for it?
I am happy for our taxes to help people who live here, I don't want to have to subsidise an influx of poor homeless sods who have no links with this area and will likely suffer deprivation because of being moved on top of the already needy people here, the 20% unemployed for example, or the disabled people forced out of our better off areas into the estates. I don't see why ds3 should for example lose some disability support because of people sent here from the SE needing extra help, which they will as poor often equals most vulnerable, or kids already fighting for a 1/10 chance of a place at ds1's SN School see that chance reduced to 1 / 15 or worse.
If people come of their own choice or to seek a new future fine, that's what we did and it worked- but this sort of mass displacement policy just works against normal, hard working people in poorer areas. as well as directly harming the chances of those moved on, and placing them at all sorts of risks.
I remember when benefit changes came in, the state booked out thousands of B&B places in Maidstone and Hastings for homeless people. I pitied anyone already there trying to get any kind of services!
Build social housing. It's the only way. but they won't as so many BTL landlords vote Tory, and rather like being at the head of a market where there are far more people than properties. Trouble is, it's the same here- 30k council waiting list.
