Sorry the outlook everyone has given you is not great, it's not great hearing not-so-good news. But it's the stone cold truth. Fact is, you're not coming here for the money - I don't think any of us expats here are (if anyone is, please PM me
immediately!
).
You might want to look at a similar post I made, my first post ever if you look in my history, that thread got a lot of good insight from fellow expats.
I was in a similar situation, just graduated with a Bachelors in Business Admin. from a good American university, etc, etc, etc. I came with an American company to Argentina, a company which gave me a friendly "salary adjustment" to adjust to the "lower cost of living" in Argentina. When I asked if I was able to get paid in USD, my boss practically laughed in my face. Apparently they got in trouble for it in years past (or he may just be talking BS). In the end, anyone I've met earning in dollars is a highly skilled person with years of experience and good connections.
I make a good salary, now that they've adjusted for inflation, and live a nice lifestyle - but my friends back home are buying nice cars and putting down payments on American-dream type houses. Don't expect that. But, I do have a lifestyle local college grads with equal degrees don't have. So I can't complain.
Best advice is get an online job you can get paid for in dollars to work remotely. Second best advice is get a job with an American company that will give you the expat package. Sad truth is the locals working for my company in the same position as me don't make as much as I do, and they have more years of experience. Recent college grads have told me about the salaries they are coming across and it made my jaw drop, almost to the level of the salary
multi-national companies are offering here. Pretty low.
Again, come here for the reasons you're coming. Enjoy it, just know you won't make US/Europe money. So enjoy Argentina for what you can't get out of the US, and that's a better lifestyle in the non-material sense, IMO.
Don't be scared off by the low salaries. But if I were you, make sure any job you get, you have salary adjustments for inflation
in the contract. Personally, I wouldn't come for under 25,000 pesos monthly at all. That's me, personally. And that's a tough find locally. Get a job with an American company that needs you here before coming. Have a Plan B.
Best of luck to you!
