because after ww2 the us identified europe as its biggest rival and aimed to de-power it in every way. under the guise of allied actions in defence and trade, they syphoned off its most valuable minds and bought off many of its industries. the eu project was heralded by the us because it meant centralising the region thus making it easier to lord over. conveniently the us demolished the middle east and shepherded millions of scum to migrate to the eu countries. it is the us alone that is the paramount reason for the continents lack of growth.
