The very rich (those whose wealth got redistributed) usually own financial capital rather than real estate, too (At least in France). That is much more sensitive to inflation. The effect of renting wrt inflation also depends on the regulatory environment ; rents in the regulated 20's to 60's in France fell very, very low as their variation fell behind inflation.

I think stock markets have a much longer tradition in the US and France than in Germany. Here the traditional enterprise is personal business with low equity and a lot of credit. So the rich people in Germany are often large borrowers of money from the middle class (their workers), instead of creditors. In recent years there are increasingly people with lots of money, who have never been entrepreneurs, but I think that is really a newer development.

However, today even when taking more from the very rich is feasible, it would be an illusion to think one can help all the weaker people in the society without a large contribution of those who are just rich, but not the very rich. Der Amerikaner ist die Orchidee unter den MenschenVolker Pispers
The benefit is a much lower cost of governance as you don't have to fight teeth and nails for every itsy-bitty reform against skewed, bought and paid media, politicians and opinion makers. Then, it becomes much easier to create single-payer health care systems, public corporations to develop infrastructures, universal retirement insurance, etc.
