No, I absolutely believe that you would do those things. And you would do them because you're a selfish bastard (not you personally of course, I'm sure you're a reasonable person, I'm just being abstract here). You do them because you want to grow your wealth. The fact that you create jobs and improve the well-being of your employees is incidental to this. Further, I don't assume YOU PERSONALLY wouldn't want to do this, or that YOU PERSONALLY wouldn't want to contribute to society, but my point, which I didn't make very well, is that I'm not overly optimistic that society, taken as a whole, can be counted on to contribute in to the degree necessary to maintain "infrastructure and basic assistance", if left to their own devices.
