Not everything needs to be a speculative commodity.
The most hard nosed Banksters brought in regulations in 1934 to create a level playing field and make sure that speculators directly felt the pain of their mistakes. Not be able to bundle subprime mortgages that they issued and market them off as A+ grade investments, as happened in 2008.
Responsible governments keep a tight lid on housing affordability.
Just try buying multiple houses in China. Good luck with that process.
