I'd also like to underscore the comment in your parent post--"good enough for me." It's not always about pay. I'm seeking a sort of "medium chill"  existence. I currently make more money that I ever thought I would, but I also have a position with a relatively stable company where I can continue to do interesting work without unnecessarily ramping up my responsibilities with each pay increase. If you offered me a job with a 25-50% pay increase with a similar increase in work time and/or stress, I'd politely decline.
A college professor that I had (a mentor), once told me that the best programmers should be somewhat lazy. I'm definitely not a 'best programmer', but I do try to automate as much as possible and be on the look out for 'gordian knots' to cut.
