Folks, there is no such thing as "free university" or "free healthcare", specially in Argentina. You pay for it just like in Chile, but you do it indirectly and you have no way of knowing how much bang you are getting for your buck.
Every time you buy an item in Argentina that costs 50% to 100% more than the same item in Chile (due to taxes) you are paying for the "free" university and health care. When you see the prices of items in the super market go up while your wages remain the same, you are paying for that "free" university and health care via the inflation tax.
But while in Chile you know how much your University education or your healthcare are costing you, in Argentina the costs for both education and healthcare are completely hidden and masked.
Finally, let's no forget that Chile tops Argentina on most if not all social indicators, including literacy, child mortality and life expectancy. Also remember that 30 years ago, that picture was very different.
