You can't expect this of people. When you do expect this, as you seem to, you end up setting up a society where sociopaths like that guy are able to rise to the top and profit handsomely because the people who made the rules just can't seem to conceive of someone who doesn't mind being an asshole as long as it gets him ahead.
This is about the US. I don't live there, I do think that and while it is super bad everywhere on earth I think we can agree the US is pulling the cart in terms of terrible. Frankly you I think the argument that "this is just how it'll be" is not one that is terribly convincing on it's own.
Yes, it'll go wrong. It'll also go right. I don't think we need to structure our society like a prison just because it has the capacity to be worse than we like it to be.
