If the EU had it just a bit together, it would flourish both economically and prestige. The entire world is looking desperately for a reserve currency, for a place where to invest or even just to go and so a master or doctoral work... and yet Germany decided to go for self-harm and censure, north of Germany all bellicose, the south of it all lost after the lost of leadership and Ursula all authoritarian... let us no mention disregarding decades of support from the oppressed in the middle east and full on board with the US policies now.
Without doing nothing the EU would had become today the beacon whether a Chinese merchant, an Argentinian industrialist or an Angolan PhD candidate, instead... here we are... So back to Buffett, true, other currencies are more desirable but no one are posed to massively stand out for now.
