“If women choose not to have children — for personal or financial reasons, or both — who is going to pay the insane amount of taxes required to keep the system working”. The answer is very simple: you and other Italians of working age are going to pay. The less babies you have, the more taxes you are going to pay, till the whole country goes collapses. In a generation your young population will halve than halve again. You can criticize your government for all its blunders but it is not going to bring more babies to Italy. Italians have to.
