Right, and you chose not to take that same risk.
But you are expecting sympathy for not being a home owner, and you now want to remedy that at other people's expense. They're your morals. I happen to disagree with them.
If your landlord raises the rent, you can move. If you want to have another child or your job moves to the other side of London or the country, you can move. You're not stuck with it round your neck like someone with a mortgage would be. But I'm guessing you don't see that as a good thing - just as people who've bought their homes won't see a plunge in prices as a good thing!
The problem lies in the council houses being flogged off and the population rising far too quickly to match the stock. And in developments like the one in North West London a couple of years ago that was actively marketed off-plan in the Far East as not having any affordable housing element. Although even then the jury is out a bit, as building all those developments has kept a lot of people employed and paying taxes, the buyers have paid SDLT into the treasury coffers etc etc.
The best way to solve the problem long term, as I've said, is to encourage people who can to spread out more across the country - thereby boosting deprived areas too - and to make city centres more accessible from more remote places whilst decent new housing stock is built. A short term hope that prices drop just far enough for you to get on the ladder (at which point your views on nice property crashes would doubtless do a pretty prompt about-face!) is not a good way to solve it.
A PP has already pointed out that the people who will swoop in and buy the cheap houses are not the sort of people you have in mind as being benefited by a crash. S/he is absolutely right. My old boss bought about 25 flats in Manchester when the last price plunge happened, all for cash, all to be let out. The people who sold them had all paid top whack for them - and all ended up bankrupt or with huge debts to pay off.
