I am perfectly aware of AFIP asking where money came from- in fact, I had to do that once in the past, and have to do it again now, due to a problem with a bad accountant some years ago.
But AFIP is taxes, and "not trusting" a bank because they follow the law and report to the government is, while common, not really an indicator that the bank will fail soon.
Most Argentines dont have enough money to keep very large sums in the bank.
Most US citizens dont have enough money to keep very large sums in the bank.
56% of US citizens dont have an extra $800 to cover an unexpected bill.
So the idea that the average person, here, there, or anywhere, is not trusting a bank because they dont have deposits in the tens of thousands of dollars- well thats not really relevant.
The elephant in the room here is the artificial exchange rate, coupled with the isolationist import taxes and duties.
This is not a La Campora thing- Macri spent $53 billion paying off dollar denominated debt. This dollar denominated debt, which has been a constant for Argentine governments for literally a century (Ok, earlier, some was Pound denominated, but the principle is the same) is the major reason why the exchange rate is so wacky, and why people demand dollars for real estate sales.
Dropping the Black/Blue FX situation would solve some problems, and create other ones.
Uruguay doesnt have much inflation, or a blue peso. BUT, and its a big BUT- everything in Uruguay costs about triple what it does here.
So, we could have easy access to dollars, and lots of crappy chinese imports, and be able to order on Amazon- but pay triple for everything. And its not like Urugayans get triple the wages.
There is no easy answer to the current economic situation.
But in the last ten years, I have seen banking here get better, easier and cheaper for the average argentine to use daily.
No, its not a place where the tiny wealthy class has huge deposits, but as a functioning part of the economy, without massive bank failures all the time, the banks here are not bad, by world standards.
