Do we need a North American currency?

<i>Canadian economist Herbert Grubel first introduced a potential manifestation of this concept in 1999. The North American Currency -- called the "Amero" in select circles -- would effectively comingle the Canadian dollar, U.S. dollar and Mexican peso.</i><p>What would make more sense would be a hierarchy of currencies:<p><pre><code> Amero /\ CAD USD MXN /\ /\ /\ individual state currencies </code></pre> That way, each level and section of government could raise the spending money it needs by simply issuing new shares (instead of punishing production and consumption via taxation of those things).

The argument for the currency is "The concern was the flight of capital from the U.S. and an option discussed was a two-tiered currency, one for U.S citizens and one for foreigners."<p>What US govt is going to give better money to foreigners?<p>On a different note, where in CA or MX are US dollars not accepted?

I didn't know that there was a need. The USD and CAD are doing fairly well, and I don't think we would want the socioeconomic and political risks of Mexico incorporated into a currency.
