Yup, it can be frustrating sometimes to watch people wasting their own time. But mostly I have seen my rich friends wasting a lot of times because they say they have nothing to do in life. I am confused by their answers, is money capable of making you do nothing? So if you have enough money, you can waste your time?
I think it's probably best to focus on oneself and move towards better outcomes from that perspective; others will often do what they want to do irrespective external influences.
