First you said inherited wealth was exploitation, now you say it can lead to exploitation. Your definitions keep changing. Did you find this in the Bible? Or was it something from Marx?
I did not say "it was". I said "what about" and "it can lead to". Reread again.
There is a tendency demonstrated over the millenniums that the wealth and power tend to concentrate in the hands of the few unless the preventive measures are taken like inheritance tax, property tax, antitrust laws, division of powers, various redistribution schemes etc ...
If this concentration is allowed to be completed we end up in a stagnant oligarchy where the powerful exploit the masses of serfs.
