I think there's a big difference between those who have less than $500 saved vs tens of thousands. My in laws are the 40% of Argentines that are poor, and I don't believe they have a single dollar to their names, in cash or otherwise. They live, consume, and are paid in pesos. You can't save when you don't make enough money to make it to the end of the month in pesos, let alone dollars.
Sometimes I think some folks forget how privileged users of this forum are. We may not be rich in our countries of origin, but if your country's pension system pays at least $1K a month you're now getting a million pesos vs. the 132K ARS minimum wage for example. The lives we live are very different than those of most Argentines, and I think this makes some of us forget that while there are billions of dollars here "under the mattress" they're under a the mattresses of a relatively small number of Argentines compared to the general population.
