Excessive bail? in Life After 60

The Eighth Amendment of the United States Constitution prohibits bail from being excessive. My question, what is excessive? Granted what may be excessive for one person may not be for another.
2 million dollar bail seems excessive, but if you have access to a few billion, that 2 million is pocket change. The issue comes from some crimes have a higher bail than others. And it appears that the judge is the deciding factor.
Then there is the whole cruel and unusual punishments shall not be inflicted. What is cruel and unusual? Pushing little wooden sticks under the fingernails comes to mind. So does pouring gasoline on someone and lighting a match.
Or how about the whole, innocent until proven guilty? Not so much these days since there are cameras and smartphones on every street of America. If you kill the President your bail and punishment will be far greater than if you killed a homeless person. Both lives are just as important, but society places a higher value on the President. And I still don’t believe Lee Harvey Oswald killed Kennedy!
