You're a complainer. Start a movement. Be the change you want to see. I'm sure there's still a pithy Twitter hashtag to be had out there for you and others that agree with you but are afraid to take the first step.
If I donate money to the government expecting it to improve things, I can't expect other people to be donating the same amount because it's impossible for me to know. If we consider people to be rational actors (as free markets often do), the free market would effectively dictate that no one would donate money to the government because that would be against their own self-interests.
Additionally it ignores the fact that I as an individual have far less influence than say, Elon Musk or Bezos with the amounts of contributions they make.
It is perfectly rational not to want to pay for other people, if they don't also pay for themselves.
It is obvious that some societal services need income from everyone, so I am perfectly happy to pay tax - as long as everyone else pays their fair share.
OTOH you seem to be blinded by some ideology that pretends that the rest of the world doesn't exist, and that only your own actions matter.
