Interesting analysis, but IMO using Europe as an example makes it fundamentally flawed. Immigration dynamics within Europe are way too peculiar and can't be extrapolated to a global level. And immigration (visa/bureaucratic hassles mainly) is probably the #1 fact that needs to be considered when analyzing the payment gap problem.
