Dani Rodrik's 'Impossibility Theorem"

Dani Rodrik has an interesting post:

Excerpt: " I have an "impossibility theorem" for the global economy that is like that. It says that democracy, national sovereignty and global economic integration are mutually incompatible: we can combine any two of the three, but never have all three simultaneously and in full."
Perhaps, more open borders may lessen the incompatibility.
