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.
People worried about inequality aren't (just) worried about the morality of consumption -- a fat cat sitting atop a mountain of cash drinking champagne and eating caviar while the peasants starve. They're worried about maintaining a democratic society, where everyone gets roughly an equal say in how things go. Highly concentrated wealth is a threat to that. Someone with enough money can single handedly change the course of politics (by funding candidates, lobbyists, or directly bribing various parties), public discourse (by controlling media corporations and through them who says what on TV or in print), and even science itself (by funding some researchers and not others).
The sleazy but short-sighted hedge fund manager bringing in a million plus a year but spending it all on yachts and McMansions isn't a threat. Bill Gates and Warren Buffett, the good investors, are the ones walking around with nukes. They could choose to blow us up at any time, and it's only through their continuing mercy that they haven't.
Wealth taxes are about disarming everyone -- good and evil -- for the safety of us all, not about morality.
