Schlack, speaking only for myself - it wasn't the economic union that bothered me, it was the complete meltdown that made way for it.
Becaused I am poorly-versed in finance and economics, all I care about is that whatever form of currency I hold, has roughly the same amount of value that it's stated to have, and that the people I need to trade economic units with, will accept it.
Beyond that I don't care whether it's Euro, peso, yen, or dollar.
