" ....opportunity I was willing to take?"
Do you really think that is a differentiator ?
Have you never heard of the right place at the right time ?
I notice you pretty much brushed off the excellent post by @HelenaWaiting above, whey they describe how they feel lucky for having the family they did.
It's not difficult to say if luck played a part or not. Because it simply does.
Compare it to a block of cheese. If high wages need one to get from one side of the cheese to another, some people might be born with a nice hole filled Swiss, others have a lump of impervious cheddar.
What cheese were you born with OP ?
And this is what I said in my first post above. It's not the earnings that folk resent, it's the attitude that often comes with it.
It's the insistence that it is all down to them. That the cheese you are served with has nothing to do with it.
Hmmmm... I could really go a nice bit of cheddar. Alas no though, because like you OP I done the abroad thing too. And no cheddar here. Also no 100k job.
