> The problem with leaving everything to private charity is that the wealthy people doing the donating dictate what counts as "public good" without you and I having any say over it.
The thing about public goods is that people tend to agree pretty closely about what they are. The wealthiest person in the world benefits from, e.g. clean air just as much as you do. You should be a lot more worried about wealthy folks who don't donate to charity and just spend the money on big luxury yachts and the like, because these folks are essentially free-riding on everyone else.

Is there some data that shows that?

We can find public goods in common for many groups, but that's actually a bad example. Wealthy people care about clean air in their neighborhood; pollution is therefore concentrated in poor areas. They don't site the new incerator (or drug treatment facility) on the Upper East Side of Manhatten.
Many needs are specific to poverty. For example, wealthy people are not subject to malaria; they are no illiterate; they don't need toilets or labor rights; they can afford college for their kids regardless of tuition; they have unlimited access to safe, fresh, healthy food. They don't need more available and less expensive health care, so they donate to cancer research and high-tech therapy and not to the medical clinic in the poor neighborhood.
Given (at least the USA's) increasingly polarized population, I don't think it's at all true that people agree closely about what should be funded, and I'll admit that fact makes my argument weaker: The danger of a particular wealthy person "donating to evil" is similar to the danger that the majority of the country votes to "fund evil."
I also agree that wealthy folks spending their wealth on luxury yachts while the public suffers is also something to worry about. Who knew? Gargantuan wealth inequalities are mostly downside for everyone but the wealthy!
Shouldn't we be a lot more worried about how political polarization might impact government choices, compared to private sector ones? Private actors who spend their own money have to pay for their own choices and are accountable to themselves in a way that political operatives fundamentally don't. I see a lot more potential for 'evil' on the political/state actor side.
