"The world markets are dominated by a few forces. One is a country with the bulk of the world's population; its population is about sixteen times the population of the most populous European country. Another is a single country with territory approximately fifteen times the square mileage of the largest single European nation. Unifying the voices of all people in Europe under one political entity doesn't zero out the playing field, but it may very well decrease the absurd order-of-magnitude scales of difference between political entities as these two juggernauts stomp inexorably towards their desired world order while the individual nations of Europe debate their own individual selfish interests."
But people aren't often rational about national ties.
