Obviously a world governance system that works is the solution, how else would you even solve problems like climate change that don't stop at the borders. The problem is the incentives, and of course the root of the problem is the lack of resources. We don't have enough for everyone, so we are pitted against each other, and the winners keep winning, thus inequality. It may be the toughest problem in the world, but nobody is trying. At best most public good projects are feel good ones, at worst many of them are actually grifts. But it's not even about sincerity, it's about power. Countries would be able to do much more, political and economical unions even more.
