Most catholic schools are much like state schools except for the religion. The issue is diverting money from state schools weakens the system and it’s academic ability. Elite schools on the other hand are well able to look after themselves.
I would also argue private schools, including catholic schools, focus on academics more than public schools. Yes, some money is diverted from public schools, but the associated cost is also diverted.
