Every country in the world has a lot of issues to fix. If we as humanity had followed this general advice, we'd probably still be sitting in caves, figuring out the perfect cave heating system instead of leaving the cave and exploring.
Harking on humanitarian issues of other countries is awkward for, assuming you are from the US, a country where life expectancy is falling, real income is falling, millions are without health insurance and freedom of press is declining. There is a plethora of other issues touching human dignity and humanitarian topics in the US and yet no one tells them to fix them first before doing X.
Sorry to be blunt, but your comment is ignorant and arrogant.
One can enable the other: space programs keep top engineers in the country, and this has big network effects that push up the entire economy...
So you end up with more money to feed starving people from! (...not that you'd do that with the $, but anyway).
Like it or not we engineers like to work on interesting problems and don't really give much thought to social issues, so if you want the super smart engineers to meaningfully contribute to a society and economy instead of emigrating or refactoring themselves into oligarchs you need to give them interesting science and technology problems to work on.
Once you have a richer economy, the problem you wanted to solve in the first place gets waaaay easier!
