“Paying” for tax cuts makes sense in the context of changing budgets while trying to keep them balanced. But no money is ever spent on tax cuts. It’s spent on the public infrastructure and services you mentioned. If you properly account for the money as being used to pay for public goods, then saying it’s also used to pay for tax cuts would be double counting.
