This is why I said "Virtually". Seriously, think about what you've just said. Do you realize that you didn't even make a claim, you simply imply that these are somehow not beneficial to society as if it were a fact? Don't you realize that you should have made an argument here, if you're going to make that claim? Making a counter argument is simple: HFT adds liquidity giving better prices to traders, and domain squatting effectively provides a set of links to relevant sites when someone goes to a non-existent site. Shouldn't you have made an argument for your position, if it was worth making a comment?

Are you really trying to derail the discussion into a debate about HFT and domain squatting?

Do we really need to think of all the possible legal ways to make money that don't help society?

How about recognizing that the point of my comment is correct, even if you manage to find some legal way to make money that "doesn't benefit society"?

While it is true that most of this discussion is a false dichotomy much of your claim is based upon the statement "Virtually every legal way I know of making money helps society" which is coming from ignorance. I doubt you have a firm grasp of how many jobs there are, what kind of value they produce, or how to quantify that value (I don't think anyone has even a basic grasp of one of these factors let alone all three).

However, one thing I don't understand is why everyone keeps talking about industries that fall largely outside of the scope of Silicon Valley. This post seems to be directed at entrepreneurs (I would guess that most employees of SV tech startups are paid more than the rest of the tech sector anyway) and it seems counterproductive to steer the discussion in the direction of the finance, law, medical, or any other industry which are (I would think) drastically different situations.
