So, yes, there is a case for single currencies in regions or even the entire world. Truly, why should people and multinational commercial institutions have to go through the ridiculous headache of changing currencies at the border? This is just pointless. Imagine if an inch meant something different in every country and you had to come to a new understanding of its meaning in order to build on this as versus that side of the border? Markets don’t like this kind of pointless exercise. The natural market tendency is toward unity in what matters (money) and disunity where it matters (competition and entrepreneurship).
So the European elites who cobbled together the Euro after many decades of planning played to that sense, and developed a reasonable expectation of a wonderful Europe united with peace and free trade, all with a single currency. It seemed like a recreation of an older, freer, more wonderful world. So why not?
Here’s why not: the gold standard no longer exists. It hasn’t existed since the politicians destroyed the last remnants of it in the early 1970s. And it was in 1970 that the idea of a single currency for Europe went from the dream stage to the planning stage. At the end of the gold standard, the idea should have been dropped but it was not. The planning elites had it in their heads that this was the only way forward, and nothing would stop them.”
