As for HFT and Goldman Sachs, people are simply bashing based on jealousy of more successful individuals in a different sector, without actually investigating the topic. Like here, where apparently many don't actually read the GPL.
As for philosophy, that's a topic in itself, but let's just put it this way - I had one foot inside the door of a monastery (figuratively), instead chose a different path. Regardless, in worldly matters I prefer a rational approach to knee jerk sentimentality and sensationalism..
