I am sorry but you can not work in the company or build a company in the country and avoid taxes. Your taxes go directly into these things. All the rest of the society has to pay taxes, they can't avoid taxes on their car via an elaborate foreign holding structure. The only way to change it to your liking is via politics, or build it in a different country respecting their rules. Get involved in local politics, especially the state of the school system and many other things are decided on a very low level that can be directly influenced by your district.

Everyone contributes and we get back free education (our universities are still good btw. and for certain topics really good) and from what I hear about schools from parents they still work, even with expanded care times. Bürgergeld exists if you really hit a rough spot. Super cheap public transit (50€ per month!) and autobahn is still existing.

You say that what Germans lack in competence they make up with arrogance, but it's really to complain about everything and be super pessimistic all the time. You can not just choose to avoid taxes, that's just highly unethical and unfair to everyone who's paying their share and super selfish. I stand by my word:

F*k you if you avoid taxes
