With all due respect...I think that the factor we are trying to maximize is not money...It is overall life satisfaction and happiness as a hacker. Personally I would choose 80K a year building my own awesome apps ,making a name for myself,travelling the world ,meeting awesome people than making 200K at xyz corp where I spend my day exchanging bullshit emails with upper management.
I'm very, very sympathetic about those goals. :) Please do more research about the app market. Most people will not achieve $80k or anything close to it as independent app developers. I wish you every success.
I'm not really in a position to share details, but for A-level geeks, there is much, much more than 100-200k to be made. It's true that most people won't achieve that. Much like 90% of sales-people's income are at sub-median levels, it's closer to a power distribution than a gaussian one.
