> as long as real estate is an investment

And therein lies the problem.

Houses can't both be affordable, and a good investment.

And if I have to choose between people having a roof over their heads, and investors being happy, the latter can go pound sand any day of the week.

I think you misunderstood me as advocating for the system that exists; We very much agree. But as long as housing is an investment, the rational thing will remain to try to pull up the ladder behind you.
