That is a good comment.

So what can be learned?

The resume could either be:

1) state needs to make speculation on water, food, medicine, energy illegal or tax it highly (well that usually does not work says Panama)

2) set "maximum" prices (A very socialist thing... also not so great as it hinders investments)

3) US & EU & Asia & EVERYONE gov NEED to buy up at least 30% of all real estate (at the price it was before the bubble) and gurantee their citizens a fair rent & energy & heating.

Guesd option 3 would be best solution.
