The EU was a sheep in wolf's clothing. It was presented as a trading union however, the elites had more in mind. They wanted, and did, turn it into a ruling union. Nations lost their sovereignty to a ruling class of elites in Brussels. Brussels made the rules that the nations had to follow. Imagine if Mexico and Venezuela were overruling the Constitution of the United States and made the laws YOU had to abide by, including welfare, immigration, losing the Bill of Rights. I think you would leave too. Heck, Washington is almost there.
