I don't understand how you could possibly say education has negative impact on society. Top universities can and do hire faculty for the purpose of research alongside teaching. Top minds performing research obviously benefits everyone as they can make new discoveries and innovations. That has the side effect of a worse undergrad education as researchers view teaching as a side gig but ultimately necessary to fund the university and it's research ventures

Individuals benefit from getting more education, but only in the sense of getting ahead in a signalling.
Perhaps an analogy helps: an individual tree benefits from growing taller than its neighbours, but the 'society' of trees scarcely gains any net benefit from that arms race.
Research is an entirely different topic that I didn't want to broach here.
For the sake of argument, let's accept that research is good for society. But we could get plenty of research without having to cross-subsidize it via education spending.
At a university level, I can't say I have studied every course or "type" of education, but it would be really surprising to me if there were any that gave nothing at all to their students
In the sense, that most of education is about signalling, and funneling more money into education just fuels the arms race.
See Bryan Caplan's Case against Education for more details.
(The part of education that's actually about learning has mostly become cheaper than ever, thanks to the power of the Internet. But unless you got a piece of paper from a university, hiring managers seldom care. (Especially outside of tech.))
So donating money to further educational institutions is bad for society. It has a negative impact.
