The problem is the system. Let us assume we have 99.9% moral people who never lie and never break the law even if they can gef away with it. Problem is the 0.1% have a competitive advantage. They will accumulate more wealth and power than the others. The others can either compromise on their morality or lose ground against their competition, maybe failing entirely. The amoral people will gain outsized power and will force others to sacrifice their values. The whole system can be corrupted by a tiny minority.

I certainly do blame some individuals who are particularly vile, like Zuckerberg and Musk, but for the most part this is just what happens in competition.
