the housing market isn't unstable, though like everything else it's in a bit of a trough at the moment. Generally though it's just responding to the laws of supply and demand. People want houses, generally in places where lots of other people want houses, so the prices go up. As VHG says, higher wages won't fix things.
What it means is that people who already have homes get richer with no effort on their part but their kids can't afford to get on the ladder themselves. Ideally the parents need to dig into their unearned wealth to help their kids out. This is what we're doing and I imagine lots of other parents too.
But you can always rent, which is what people in other countries do. You don't really *nned* to own a house - it's that perceived need that is driving the prices up.
