Property prices in Poland surge with two cities now rivalling cost of Rome

Because of retarded politicians. Allow private ownership of 1 accommodation and aggressively progressively tax every next one owned. Ban non-private entities from purchasing accommodations or land (except for immediate business related investments of course, i.e. business related construction). Problem solved.

Henry George speaks of this. We need to tax land

Everything works as its meant to – rich get richer, common people suffer more, just like USA
