Communism does not work. Russia proved this. Human nature runs against Communism and it fails, spectacularly. CAP - Common Agricultural Policy is one example. Balanced prices, quotas to produce, products to produce are set out for our farmers to produce.
Balanced prices means some products are permenantly expensive.
Maybe better trade. But that is the reason for the Common Currency. Ulterior motives might be rife. So what do we do. We say, Wake up Europe.
