Actually, hold on, jump out, meta-level question: why are you privileging the hypothesis that “voting with their feet” represents a reflectively-coherent all-else-equal preference anyway?
Well, for one thing “voting with one’s feet” doesn’t have the rational ignorance problem that voting does.
Which is not evidence regarding migration as a preference indicator.
What definition of “preference” are you using there? If I pick the vanilla rather than the chocolate ice cream, would you agree that this is evidence regarding my ice cream preference?
If I pick the vanilla rather than the chocolate ice cream, would you agree that this is evidence regarding my ice cream preference?
That depends: what system of incentives, ranging from monetary payment to a gun to your head, is acting to make you choose vanilla? People’s real preferences are the ones they possess and exercise without external compulsion or incentive making some possibilities easier than others.
Not if those same factors also show up it the decision you’re planning to make based on those preferences.
They don’t: collective, political decisions are simply not supposed to take individuals’ incentives into account as inputs, but instead to change those incentives as output.

That’s still evidence that the value of said incentives is larger than any preference I have for chocolate over vanilla.
Which is actually why those incentives are confounding factors when we’re trying to measure your actual preferences.

How did we go from “preferences” to “incentives” and what distinction are you trying to make here?
