What was the USSR? It was a group of countries with related cultures and histories dominated by a central government. It used one common currency and had one banking system. It failed terribly.
What is the EU moving towards? A group of countries with related cultures and histories dominated by a central government. It is using one common currency and it is on the verge of having one banking system It will fail terribly.
Why is the EU moving in this direction? Like the USSR it would like to have a social and economic Utopia.
Its leaders and its population are under the strong belief that commonality of currency, banking and law will produce this Utopia.
The people of the EU do not want to believe that human nature with its inherent greed, corruption and nepotism (favoring one’s family and friends) exists.
Like patients with dreaded diseases they want to forget reality and believe in the fantasy of a miraculous cure.
Yet, the sciences of psychology, sociology and the facts of history all point to the fact that there are no miraculous cures for the problems of society.
If the EU becomes a replica of the USSR it will continue to exist for a few decades, but as the people in government become entrenched they will pass laws that benefit themselves and their friends.
As the workers and business owners understand the laws the bind them, they will find ways to circumvent those laws and receive the same or better rewards for doing less.
As in all societies the elitists will push down their less gifted peers. An aristocracy will result. Ultimately, the new EU/USSR will collapse or fall under the weight and force of the large lower class.
The only solution to the problems of economics and societies is through the formation of very small countries. Eventually, mankind will be forced to accept this solution.
