If the world expected everyone to be good, then it wouldn’t be bad.
You’re naughty because everyone else is. You play by unethical rules because everyone else does. And gets away with it. (The ongoing farce of bailing out the rich in the world of money is a current illustration.)
But if everyone expected to play fair and you didn’t, you’d get found out quickly. That’s natural.
What this means is that if there is a problem in the system (and there is), it’s a big problem. Everyone’s contributing to a system built on a culture of bad ethics.
So, how can I be optimistic? Because people are changing. Its a process of realisation. A gradual enlightenment. Either through choice or necessity. Once humanity reaches a tipping point of realisation, the world will change fast. And that tipping point is not far off.
