You can use such a justification to argue against any far flung efforts of humanity - and many have for a very long time. This sounds like: we must solve the disparity between rich and poor before we invest any efforts elsewhere. Since that's clearly not happening, doesn't that imply that we can't make progress in science and space? I find it interesting that often those making such a claim don't devote their lives to fixing the problem in the way that they're asking for. Sounds like a recipe for cynicism and despair.
