Thank you for the chart. Germany is further down the list than even I thought, admittedly. How sad ist that. Here I thought that at least Germany having a good social safety net and free university would mean it is somewhat easy to pull yourself out of low income if you are intelligent and have the drive, as well as parents who gave you a bit of encouragement in your early years. Seems like even that is harder than I thought.

Do you have one for mean income to upper class by chance? Even +1 Std Deviation move would be significant in terms of wealth building.
