The inequality is also bad for the rich since they end up getting eaten.

The kind of argument the OP is trying to make makes no sense to me, the only reason I see for us to "trust the market/system" is because it promises the most efficient allocation of resources, fairest compensation for value provided and opportunity and development for all. If it fails, it fails. I don't see how obcene inequality and all the problems of human misery that comes with it(which goes from insecurity to violence to even wars) isn't an instance of economics failling its own proposition(I will admit it does like 1% of it, tho).

The most efficient society would be one where money and resources goes where it's needed and that it would create virtuous cycles(e.g.: take people out of misery -> they become economic agents -> everyone's work serves needs of someone else -> development -> world GDP increases -> humankind is able to do more things -> society gets star-wars-like capabilities -> more people more happy)
