If everyone had access to the same kind of tax advice that minimised taxes for the rich, I bet a bunch of loopholes would get closed pretty quickly. Some publicly available templates and simple to follow guides would encourage governments to act when they see a general shortfall in revenue. When new loopholes emerge, rinse & repeat. Maybe everyone would pay their fair share then
I'm not sure governments would act on a shortfall in revenue. Some governments seem to just consider money not real, just add a couple trillion to the debt and call it a day
