The industry is trending upwards, but inside of companies pay doesn't tend to match industry increases. If I know that jumping ship would increase my salary because my raises have been barely matching inflation, you can bet that's contributing to chances I burn out.
Inflation so far is 2015 is well below 1%, and 2014 was 0.8%[0]. The PDF in the GP shows an average salary increase in tech is about 2x inflation for 2014 (but half of those increases are raises and only a quarter are from changing employers).
But more importantly, how is knowing that you could pick up and go somewhere else for a 10-20%+ raise going to increase burnout? Either your pay at your current job is enough to warrant whatever stressors you may have, or it's not. I'd be in a much worse place emotionally if it was either my current job or the poor house.
