That isn't the point. The ultra wealthy are using all that extra cash to buy expensive apartments and housing and leaving them empty or renting them out. This 'demand' for property raises the price of it. Since rents track property prices, rents go up too. As soon as the ultra wealthy have a fat tax bill due all that property comes on the market again. Together. Crash time. Sane prices once again.
