They need it.
I spent a couple of years down there in the mid 2000s and they need all the help they can get.
It's a shame, they have lots of resources (good growing climate for livestock/grain, lots of flat/clear land, some mines (looks like aluminum, lead, copper, zinc, silver, gold, lithium and boron), but epic graft and mismanagement from the government.
As an example, when I was down there you were supposed to get your Documento Nationale de Identidad if you stay there for more than 6 months, when I went to get mine we brought a dozen pastries (they call them Facturas) for the clerk at our appointment and everything went smoothly, we were in and out in an hour. I was told that if we hadn't brought them, we would have been there all day (despite having an appointment).
We received letters and packages for about 180 people (about 70% from the US and Canada, so we would go to the post office weekly and usually we got 2-3 big sacks of packages. We always brought 2 dozen facturas and they charged 300 pesos (about $100US at the time) in "import/duty fees" every week (note, that went into the pocket of the supervisor, not the cash drawer
).
One day we were late for our appointment at the post office, so we didn't stop to get facturas.
The lady started opening packages to verify that the customs declaration was correct, got up to 900 pesos in fees and said "Chicos, are you sure you don't want to run down and get facturas?" We took the hint, went, bought the usual 2 dozen facturas (10-15 pesos?), came back, paid 300 pesos in fees and off we went.
