In 2010, being an independent developer for a startup in the US in argentina meant a 2-3k monthly wage. It is now at 5~6k, and plenty of opportunities to make 10k monthly.
Bear in mind this pays <5% tax and you can maintain a whole family, pay for a house, food etc for 2k a month.
This arbitrage has always been there and its become way easier to manage after the remote shift.
