What i mean by that is the following. The US used to be a collection of states, each with its own rules and currencies, etc. But over time it was necessary to tie together all of those seperate States into one country under the Banner of the USA. With a powerful federal government that controls monetary policy, regulation, Foreign policy, and that deals with disagreements between states.
The European union, in my opinion, is trying to be like the US without being the US. aka, having a common currency, but no common fiscal policy, etc. And we have seen that this has lead to a lot of problems lately (see greece, etc) Does the EU need to become more like the US, strengthen its central government and make each of its countries more like what the states are in the US? Or is there something else that the countries in the EU need to do?
