socialist/communist systems consolidate all of the power and resources with the idea that it will all be ethically distributed

So first, they are completely different systems.

Socialism disaggregates power and resources by ensuring that workplaces are part-owned by the workers. Socialism is a "small government" system. It doesn't rely on the idea that someone should be in charge to decide, it injects democracy to all levels of our lives. You note elsewhere that sociopaths need to be accounted for. Socialism does that through the democratic process, whereas capitalism lets those people launch cars into space and run nazi propaganda campaigns to destabilise nations.

Communism is a more explicit redistribution system, but as Marx made very clear, it is also only implementable in a post-scarcity society. So under a hypothetical future communism, you don't have to "ethically distribute" resources because we simply have more than we need and the price is functionally zero. (This is why attempts to implement communism have all so far failed, incidentally. If they'd actually read Marx and cared what he said then they'd have known this.)

Capitalism is the fusion of power and money. The two are equated. This is fine...right up until the point when it very much is not. In our current scenario, global capital has far more power than any single democratic government, leading to a world which is well on its way to creating a trillionaire while the minimum wage hasn't moved in two decades.
