I don’t agree ‘it has the high ground’. It is given it the high ground. Capitalism is all about high risk that can lead to high reward. If the rules are changed to low risk will always result in high reward for a few individuals, you end up in a system like this.
However, the system only works when the democratic systems are sound, and let’s be frank here, the democratic systems of the USA are nowhere near sound. The fact that, what you rightly addressed in your post, capital has more influence in politics than votes have, is a red flag.
So, don’t blame capitalism if it is your political system that is at fault. Because if you don’t fix that, no other economic system will function accordingly.
Again, not capitalism, the economic system, but political ideologies that cause it.
