When you think of these things idealistically it sounds so wonderful
One World, equality, no more wars, trade on equal terms, the elimination of the nation state, no more poverty, free movement, freedom of expression, free love
But superimposed on the reality i fear this is Dangerously idealistic and frankly is probably 200 years before its time at best
Human nature and our current state is just not ready for that kind of scenario, which is more likely to backfire and lead to oppressive dictatorship and enslavement of the populace.
If you think this unrealistic then beware, i am being no less fancy full, less haste for heaven is my motto, it will come to all of us soon enough
