Argentina is suffering from high inflation due to odious debt owed in US dollars to the IMF and Western vulture funds.
Argentine right-wingers insist the "solution" is to abandon monetary sovereignty, adopting the US dollar.
Economist Ha-Joon Chang said "this is the worst idea" and is "insane":
"If you want to adopt the dollar as your official currency, you should apply to become a colony of the USA, because that’s what it makes you. Because this means that your macroeconomic policies will be written in Washington, DC.
...
"Argentina unilaterally accepting the US dollar as a currency is insane, because you don’t have labor market integration; you don’t have fiscal transfers.
"It’s not as if the [North] Americans are going to say, 'Oh you cute guys in Argentina, now that you want to use the dollar as your currency, we will accept more immigrants from you; we'll give you some money'. No.
"This is the worst idea".
