What matters is the turnover of inheritance.

If you have the same 200 families holding all the wealth for 500 years, you have a problem (like several countries in europe).

There is nothing wrong with a hardworking person to reach wealth, and for heirs to keep it, if its properly managed. The issue is they should be able to lose it thru squander. Bail outs, lobbying, regulatory capture, prevent that natural ineptitude from taking place (securing thru connections what heirs couldn't do like their predecessors....that is, satisfying customers or creating shrewd innovation).
