You said the quiet part out loud. “Equally benefitted” is another way to describe equity.

Providing them both with 10 hours of language classes will be equality but results won’t be equal.

Again, you’re just arguing for equity and against equality. Equality and equity are fundamentally incompatible, since achieving equity requires unequal treatment. Presumably your example ends with the Italian person getting more than 10 hours of lessons because of his nationality. You seriously need to acknowledge that you’re advocating for one person to receive better treatment because of their nationality, and consider the consequences of that being an acceptable practice. You’re trying to reverse over a century of human civilisation’s progress.
