Total UK housing stock is worth 10T GBP vs 2.2T GBP GDP output. Don't think any other country comes even close in terms of skewed reliance on housing as a driver of wealth. I can't imagine the reduction in net worth of citizens (65% are owners) when house prices crash 20% due to higher interest rates. That would be 2T of the 10T value - almost the same as GDP.
Anecdotally, every British person I know has a common long term goal - save enough money for a 5-10% deposit on a mortgage. The incentives here are all wrong. You build wealth by investing in a house & taking 90% loan to value mortgages instead of actually working harder. Work is just a means to save enough for deposit & afford a mortgage premiums and maybe 1-2 holidays a year.
People complain UK is stagnating. Companies don't want to IPO in London. I can tell why - banks don't want to lend to SMEs. 50% of their lending is actually housing mortgages. Same with people - they would overwhelmingly invest in a house rather than own company shares. Housing is the root cause of malaise in the economy. Take away the incentives to own a house by building more homes, increasing mortgage rates and eliminating government policies helping people to buy & this country would just become much better
