This is just the sad indicator how the world works. On one side you have people dying of hunger and living in utter poverty, and on the other side you have people shitting in the gold plated toilets and spending per day enough to feed several thousands from the first part of sentence on some utter nonsense.
Well this is one part that we can't really do anything about. People born to that small percentage would likely die there as well. You don't see too many rich and powerful lose their wealth right? If anything they just become richer and richer
There are things that can be done, like wealth redistribution. The question is whether those activities solve more problems than they cause. Socialism has a long history of requiring oppressive violence to enforce, and results in a lot of corruption as the people tasked with redistributing the wealth often don't abide by the laws they create, thereby breeding resentment. I don't believe there is any purely capitalist, free-market nation, all the richest countries have some form of socialist tendencies with redistributive policies, the question is just finding the sweet spot between what is too much to be destructive and what is too little to perpetuate suffering.
