Possibly? Yes. But for every Argentina, there's 10 other countries where you'd loose (far more than) 40% to social security, taxes, and middleman that will handle all the paperwork for for you, particularly if we are talking about "real, productive swe jobs [that] earn enough to support not only themselves, but everyone around them as well making the place they live in a tiny bit better."

I basically have one such job, living in a stable but bottom of the table EU economy, and 40% is exactly the ballpark.

People love to rationalize tax evasion like that.
