You can't discuss pensions without analyzing the whole concept. Jubilacion in this country is not just a social security, it's also a state welfare program.
More than 60% of jubilados charge the minimum.
To pay for this, the Aportes Jubilatorios come from a labor force where 42% is en negro. That means zero contributions into the system. Where did the other 18% of jubilados come from? Stay at home mothers, family caretakers, etc. People who never even worked a paying job per se.
Do you know what you receive in Social Security in the USA if you have below 40 credits (10 years of contributions)? Zero...absolutely nothing.
Yet, in Argentina, they at least get a minimum state welfare. Now you could easily say, but the Jefe didn't offer me the job en blanco and it's all a horrible exploitation of labor. A couple of years ago I would have believed that, but today I cannot even begin to describe to complete complicity at virtually all levels of commerce in paying everything possible en negro. It really is a countrywide cultural phenomenon rooted in the total distrust of the state apparatus.
As far as I'm concerned, you can't go out and riot for increases to government welfare at the Casa Rosada next to the storefront sign saying 20% discuento effectivo. The government could easily placate the masses by printing the deficit in Jubilacion contributions but then you are going to get other protests saying "stop the inflation".
Either the program needs to be adjusted to paying contributions or the labor class needs to contribute their fair share.
