As to what I would actually want to pay taxes for it is to build new things and achieve new things as a society. I never want to spend money on 'fixing', it is needed, it has to happen, but that doesn't mean I have to like it. Building new things however I am 100% for. Get us to space. Find new particles. Help foster the arts. That is what I want my taxes to go for. So, yes, fund things like this if it is effective because we have to but you won't get me to say I want to spend money one this.
Ideally government work would pay well enough there would be no temptation to accept bribes, or declare bribes legal through awkward loopholes like campaign financing.
