Is it really necessary to cover 100% of real costs? Where in the developed world is this the case? And where are the efficiency measures one would expect from a free market capitalist?
I think that in most of the developed world things like education and public transport are considered social goods that don't repay their investment directly, but benefit a country in other ways: better educated people do higher value work, and public transport reduces pollution and traffic. It's not expected that they be self-financing or run at a profit.
Milei's claimed ambition for Argentina to be like Ireland makes me laugh, Ireland provides free education through university.
As for the efficiency measures one would expect, this is to me one of the most shocking aspects of this government. I've never seen such a bunch of work-shy ministers in my life. The minister for health surfaces after 3 months to tell us not to wear shorts because of dengue. The education minister (whoever he/she is) threatens the universities with audits, why wasn't this being done already? All his tarotist minister without portfolio does is troll at every opportunity and take free trips in the presidential jet (yes, normal airlines are no longer good enough anymore), his defence minister got some selfies in an F16, and Milei himself prefers trolling and spewing hate on Xitter to actually governing.
I watched Milei's "cadena", it was nothing more than a gabbled monologue. A number salad. No attempt to explain his project, plan, or relate to the people who elected him. Zero empathy. Crowing over a primary budget surplus that might as well be a rounding error. At least he didn't mention the "caste", that was the one positive takeaway I got.
One of the comments on social media explained it like this: you receive your salary, and declare you're not going to pay your rent, gas, electricity, credit card bills, so you believe you have a surplus. Substitute pensioners, provinces, education, health, subsidies for transport for the previous list and you've encapsulated Milei's project.
