"A world currency imply a world government, a world tax policy, the same level of wages and equal rights (costs) throughout the world, which in the coming decades is a utopia."
I disagree with this assumption. You are describing a CENTRALIZED world currency. The rest of your observations flow from this fault.
I would agree with what you had to say if we were dealing with a UN-issued world currency, or something like the Bancor which they used to talk about...
Indeed, well put....
The TRUE concept of decentralization is something that illudes a lot of people still.
Unlike communism, it is viable, and not only viable but the way forward. Decentralization is a concept that even countless people using the word on a daily basis don't grasp what they're talking about because the paradigm is so different.
Well said!
