The problem with differentiating between the "good investor" and the "lavish lifestyle guy" is that the good investor is actually the one that you (rather, Piketty) need to be most worried about.

At the same time, it would encourage the companies he buys from to expand their production and invest. Now, some people may wonder what investors/financiers those companies can find if all the rich guys sell their investments to consume. Well, those companies can always go to banks, which have an essentially unlimited capacity for funding real-world investments.
