There's a lot to unpack in that article. I ran it through Google Translate to get a few quotable sections:
"...the charging of fees at National Universities [...] for non-resident foreigners"
This is a bit strange, since I expect the foreigners in question are mostly Mercosur citizens (and mostly Brazilians, I would expect), and therefore entitled to 2 years temporary residency in any case (after which they can apply for permanent residency and citizenship, of course). So, in essence, the university-related part of the announcement is hot air?
For "...the same policy for the public health system", this would have a bigger impact, but it's such an obvious "tiro al piso" I don't know why it hasn't been done already nationwide (it has been done in certain border provinces). And "we are saying goodbye to health tours..." makes me think the government doesn't understand the concept of health tourism; back when the Peso wasn't enormously overvalued, certain clinics (ICBA for one, I expect there were more) offered treatment for paying foreigners. I understand it was very lucrative. And very very high quality. So, yes, goodbye to all that.
This will be interesting for the 3-month visa run crowd: "Entry into the country will also be denied for irregularities in the documentation presented by people at Customs. Those who try to enter with false documentation or who are suspected of having a different reason for entering than what they stated during the immigration process will remain on the other side of the border. A prison sentence is being imposed if the foreigner violates the ban on re-entry into the country.”
