That's just not true at all, immigrant communities are the ones who couldn't afford maids. I know dozens of 3rd generation Italians in Argentina who have secret recipes passed down from their Italian abuelas that are amazing. Argentina is absolutely chock full of Italian restaurants that make their own pasta, along with pasta shops that sell fresh homemade pasta around every single corner (something you don't see anywhere else in the world but Italy and Argentina). Just because Milanesa is popular doesn't mean the Italian food isn't also plentiful and good. And by the way, Milanesa itself is an Italian dish, and in Italy it also has a side of papas fritas. So even THAT is VERY italian.
This country has the best Italian food that isn't made by first-generation Italians in the world. It's much much much better than the Italian food in the Anglo diaspora and has retained a lot more of its original characteristics, likely due to the much higher concentration of immigrants from Italy. The only big difference is the Pizza, but Argentine pizza has taken on its own identity and is now very much its own, unique thing, which is also a sign of a healthy gastronomic environment, since most other Latin American countries just serve US-style pizza.
