Correct. In fact if a billionaire spends money on a mega yacht, that's much better than something rent seeking like lobbying, and for those who care about share of the economy going to the top (vs the total picture of the pie) at least they're not buying up more productive assets. Also yachts employe people. To build them, to man them, to repair them, to fuel them etc.
