The only real solutions to this problem (such as scrapping the preferential tax treatment of housing ) involve house prices falling, so I doubt they will happen under either government.
I'm fortunate enough to be able to afford a house (thanks to stock market investments) but as an investor would never put my money into anything as overpriced as our property sector. The only way I can see it holding up is for governments to provide more subsidies (watch this space), and greater financial innovation on the part of banks and mortgage brokers (think sub-prime). Or wages could rise (leading to inflation, lower corporate profits, lower share prices).
Its all redistribution one way or another. Just depends who you think should be the worthy recipients.
