> In the 70s and 80s even 90s someone on a teacher's salary could own their own home in a major world city - say London. You can still have that. All you need is a real estate tax.

No, tax won't help. The reason is because the population grew and the amount of land available stayed the same. (Google London population growth charts).
Real estate prices are going up everywhere - including places with negative demographic trends.
