I am a repat Argie and I agree with Sara's figures.
I know of a few Argie friends who have those types of income. There is a wide range, though... One should look at it case by case...
Person #1, 30-year-old, economics college degree, earning $10,000/month at the national version of the IRS. He is a manager, but not a mid-level manager...
Person #2, 40-year-old secretary to the CEO, college degree, earning $8,000/month at a French company
Person #3, 50-year-old, engineer working independently as a consultant, earning +20,000/month
These are all Argentinians...
I then have a VERY LONG list of Argie friends who earn anywhere between $2,000 and 5,000/month... but, indeed, there are salaries around $11-14,000 for some mid-level managers at some places and, definitely, much higher salaries too...
