The tone of this post alone tells me you’re driven by hatred/envy of the rich than concern for the poor.
Free market capitalism has lead to the largest expansion of living standards. Like you, I agree capitalism is the worst economic system, except for all the others.
What it tells me is that you have no idea who I am or what I stand for.
Why would I envy people who are destroying society, causing misery for billions, driving things like migration and conflict as well as causing the collapse of ecosystems and a mass extinction of species not seen since the dinosaurs. Yep, I really envy them! If anything I pity them for not having the intelligence to see the damage they're doing. If they do know and just don't care maybe that could be described as hatred, but even then maybe that's a bit strong. More annoyance and frustration.
Capitalism hasn't lead to the biggest increase in living standards, that was science and the enlightment. The Incans believed that the reason for their success was brutally sacrificing kids and guess what happened when the 'Gods showed their displeasure'? They sacrificed even more kids. Had absolutely fuck all to do with the success or failure of their civilisation but they believed it. Capitalists show the same thinking - things are going well it's all because of capitalism, things aren't going well it's because we need to add more capitalism.
As has been pointed out we don't have free market capitalism in it's true sense because so many things are provided outside of that system. And most of those have the biggest benefit for living standards. And almost all others are subject to regulation and laws to specifically prevent abuse by the free market capitalists.
I would love to see in a thousand years the reaction of people then to how we're living now. They'll look back on it with the incredulity we show to sacrificing kids.
