I wonder if that holds true worldwide.
Also, more money also reduces stress in other areas. It's fairly easy to spend money to reduce stress in your life, if you have it; on the contrary, money being tight is a major source of stress for most people, even if they don't realize it.
If someone find their current job too stressful, it's probably the company and the specific people you work with, not the level of the technical work. If so, finding a similar or slightly higher level job at another company with a better culture is probably the right move. (If I'm wrong and it really is the technical side of things that are stressing you out, then obviously this doesn't apply!)
Otherwise you are correct, stress is more self controllable.

When you start having phone interviews, make sure you ask the hiring manager this question:
How many people do you manage? how many people have left your team (for any reason whatsoever) in the last 12 months. This number is quite telling. Good companies and good teams don't have attrition and don't have problems keeping employees.
Not always true. My last team was atrocious but nobody ever left because they were held all captive on their H1-B.
To explicate a little, I've found stress mostly relates to the expectations of people around me, and has very little to do with the difficulty of what I'm being asked to do.
