It's clearly a tool of capitalism and is used to perpetuate the economic power of the capitalist class against their workers, but it's also a major opportunity. The building of a pan-European identity separate from the old nationalist ideals could be used to create a European Federation, and later a unified socialist state in Europe instead of having to incite proletariat uprisings in each separate country. In other words, the EU sucks, but it's potential to unite the workers of each current state also shouldn't go to waste.
