I do think people should pay their taxes in order to fund the next generation of universal prenatal medical care, education, etc., but having them work for local companies for 20% of the market rate means they only have 20% as much income to tax, so we can only fund 20% as much education and medical care. You might think this would be compensated by vastly increased profits for the companies, but it isn't, because the low wages mean it's profitable to set people to work on low-value projects.

So, no, I don't think people "owe" working locally. If they owe anything in exchange for free education, it's realizing their full human potential and being generous with their time and money.

Now, go donate to Library Genesis and Sci-Hub, so the next generation can have free education not only in Argentina but everywhere in the world that it's legal.
