This attitude that the market must always go up has never worked out historically, just makes the eventual reckoning that much worse.
Fortunately that mentality means that renters like my wife and I who want our future kids to grow up in a good house in a quality school district can just keep saving money, waiting to capitalize on the inevitable normalization when all the speculators and eggs-in-one-basket people fail to learn from history... again.
Just inflating the bubble further, as every European bank and government is doing, to make existing property owners richer on paper and get their votes, is not a viable long term solution.
IMHO, it can't pop sooner. Houses should be for living, not for speculation and hoarding wealth. The younger generations have been screwed enough by the old established wealth hoarders.
Otherwise, the number of people in that "put their life savings as a downpayment on an overpriced house" category is only going to grow, making the problem worse when the collapse eventually happens.
I think we run into real problems in America trying to protect people from the consequences of their own bad decision making. In addition to being deeply patronising, it eliminates so many of the normal incentives to be responsible and pushes up risk appetite across the board.
If individuals make poor investments (whether on a house or gamestop otm call options) they'll learn their lesson and move on. There's enough of a safety net in America to ensure no one truly goes hungry from bad luck (and before you point to homelessness- that's a complicated issue intertwined with drug addiction, mental illness and in some cases a free lifestyle choice)
