You can blame the root cause of all this social negativity on the ultimate law of the universe — probability balance. And as creatures of the universe we humans cannot escape its dictates.
So what is this probability balance thing? It is something that we all sort of know to be truth, but as far as I am aware it has never been “formally” stated.
Probability balance simply put says that creation and good, at some point in time, must be offset by destruction and evil — stars are born and stars die, people are born and people die, peace is offset by war and love by hate. All one can do is to try and stay on the positive side of the balance equation, even though there is no possible means for holding back negative offsets.
Thus the motto of life has got to be, this too shall pass, words to live by as we ride out the bad times and work toward better days.
