Given the typically disproportionate cost of housing in most areas, I'm in favour of utterly massive protectionism/nationalization of housing infrastructure and other non-tradable goods fundamental to human need; disallow all speculative investment in property (foreign or otherwise), voila, instant price drops and quality of life increase for anyone who doesn't already own a home.

What isn't usually mentioned in discussions like this are the resulting lack of returns on investment on behalf of future retirees, but to be honest, I can't imagine why anyone would rationally expect an economy to be stable enough that they could plan not to work for 40+ years of their life - looking around the world, this delusion is almost exclusively a Western phenomenon; there are other valid models.
