What's the point earning more money if its purchasing power isn't all that much more
You have a point if you're talking about migration, but if you plan to work abroad on a temporary basis you might benefit from such differences.
and you're going to end up waking up one day and realising you're 35 years old, unmarried and going nowhere in life?
Oh, but it's not always a bad thing to be thirty five and unmarried you know. I know a thirty nine year old guy who has had four marriages, and five children with three different women. He always has problems with money because of his situation, and he earns twice as much as I do.
I'm careless, don't have *that* much stress so I'm reasonably happy. So it's not about where you're going, it's about how you're doing.
