Well sure. But when it isn't "parasitic", there's no reason why that shouldn't be something to applaud and look up to. Unless you want to give Trump some suggestions, I think the idea that Bloomberg's career has been "parasitic" is transparently basis. Not that you necessarily meant that, but it was implied...
Not entirely, no, and probably less than many other billionaires, but it's still far from something that I'd find remotely worth applauding. I mean, whatever good he's done, he hasn't exactly done it out of goodness of his heart, has he? If someone seeks their own personal gain and happen to do some good in the process, good for them and for society, but that doesn't make them saints.
Indeed, it's a common truism to say that this attitude represents the quintessence of the American spirit. There's a lot I like about American culture, but that's not one of them.
