Once you're qualified, it's natural to go off and place yourself where you can make money.
As an anecdotal example, in my local practice, there are a lot of Eastern-European and now Greek dentists. They're excellent and came here to make more than they would at home (and prop up the NHS whilst they're at it) - I do have a concern that there's likely to be an impact on dental care in their country of origin though. I know precisely that has happened with nursing.
