That's a social/political problem and needs a political solution. I rather find myself in a situation where we have the means to improve everyone's lives but don't do it yet than in a situation where we don't have such means at all because we didn't pursue them because we were so afraid that it might only benefit a sub-population. There will certainly be countries on the world where the benefits of the technology will affect only a tiny elite population, but I think in many other countries it might benefit a much larger chunk. Any country with a public healthcare system should consider doing germline edits if they decrease the risk of very expensive chronic diseases.
