There are more assholes than good people because assholery typically delivers better results in terms of wealth, power, and status, and good people have to accept a lower social status in order to maintain their goodness, but most people don’t fall into either category.

But the vast majority of people fall into an apathetic middle ground where they don’t really think too much about any kind of moral consistency and act according to paths they’re already on and the rules those paths require.
