The insidious is that even if you somehow created a 100% inheritance / wealth transfer tax (that is, children would inherit virtually nothing from their parents), people with wealth would just rely on creating exclusive networks that the have-nots would not be able to join. Now that I think of it, sort of like the patricians and plebeians of Ancient Rome. You could become fabulously wealthy as a plebeian, but you would never be able to become (and enter the network of) patricians.
