Quick rebuttal to both you and Paul Graham: "Okay, we get it -- it's both position and velocity. But when people talk about "income inequality", trust me, that's exactly what they're talking about -- both relative income and income mobility. In other words, they're not as dumb as you think - they're just simplifying. Go that? OK, good. Because we'd really really appreciate it if you'd at least begin to acknowledge the core issue at hand. Instead of just throwing your hands up the air and saying, in so many words, 'Yes, salary differentials kinda suck but hey, anyone can, in theory, apply for a software engineering job at Google or a YC startup -- so it's all good.'"
