As a non-Argentinian, I thought it was great!
Perhaps as a fellow canadian, who also knows what the IMF is, I can sympathise more.
I get the song, and the viewpoint, though viewing your profile helped.
Political satire/commentary can be tricky.
Also, with a similar recording setup (minus the aardvark) I can also sympathise with the song, rollicking tempo and all.
The mix - too much panning for my taste, although I am listening on headphones.
What is the organ?  That's not bad for a soundfont, I think.
Liked 
the direct guitar, gives it a nice 'sproingy' quality.
Vocals are a
little Billy Bragg-ish.
Suits the song, though.  At least you didn't go the Bruce Cockburn route! 
And about Soundfonts - do you buy yours, or go the freebie route?  I'm pretty sick of all the good ones I got off Hammersound.  They're good enough, especially a great Rhodes that I found, but I have been tempted to try some of the commercial ones.
