Borrowing money from the IMF (or EU) always comes with massive strings attached. They want control of fiscal and social policies. Just ask the Greeks or Argentinians.
For El Salvador, the IMF comes across like that drug pusher desperate to inflict another fix on someone who is trying so hard to get clean. It's not a good look.
Know it very well.
About El Salvador, I am not sure it's all clean like they are trying to tell us but at least they give us all an idea of how a nation can be ruled, with no CBDCs (like we are all at risk in EU)
