No, please go on.. Because what you are saying in reality with that statement is that
A: property in your community has really poor vaiue compared to Europe and
B: JR could take his €2.000.000, exchange them for $2.600.000 and buy 26 homes in your community with the same money as you claim 1 home in Germany of the same standard costs (which presumably you have no facts to back right?)
Also, inflation and property value is not the same, properly value fluctuates independenty of inflation which is a economical term that shows rise in prices of goods and services in a set (national) economy over a period of time. Usually between 2-5 percent annually in western world countries with a stable economy. This is why you should raise your prices 5% annually to keep up with inflation, you do not adjust your prices according to properly value in your community.
You would be onto something if you ONLY could buy property and nothing else with your earnings, but that is off course not the case.
When for example vinyl and plotters, printers, computers etc cost just about the same in Europe as in the US, 2 million euro WILL have the same buying power as 2,6 million dollars, not $100.000.
