Their finances aren't in great shape, but if you think the ECB will let that happen, I have a bridge to sell you. (And the need for a bailout is far from a foregone conclusion.)

That's not a measure anyone uses for anything, so not sure how that's relevant.
But sure, let's go with the idea that Mississippi is "better off" on this metric. GDP per capita (which is a mean, not a median) is not a good proxy for standard of living. A French person working 35 hours per week living modestly might be much happier with less money than someone from Mississippi working 3 jobs, 6 or 7 days a week, for a total of 60 hours, who doesn't really have the time for "living" at all, modestly or otherwise.
(I'm being generous to you when I say "might be" there. What I really mean is "almost certainly is".)
