The Government is not "being paid" tax dollars[^0], it is (in principle, at least) spending and redistributing wealth in ways which benefit all citizens. UKGov releases these reports, for example

Unfortunately, it really is too complicated. A doctorate in economics might get you a decent way towards understanding the good that taxation provides, but given that economists still have differences of opinion, maybe not a complete understanding.
