A big part of the issue is because the US effectively controls the world's money printer due to the use of USD as a reserve currency. This necessitates a trade deficit so that other countries can actually have access to USD.
The solution to that problem would be the introduction of regional bancors. The EU needs one for internal use. Technically the euro is a very "shitty" bancor which rather than being used as a unit of account, was directly adopted as a currency in each member state. In theory each country should have had its own branch euro which are then exchanged via the bancor. i.e. regional currencies. The bancor is actually just a barter exchange for currency. I mean that is what it boils down to.
