The older I get, the more I understand those people who only did enough to keep their job. I used to feel it was an ethical obligation to do my best, but I'm realizing that that is a one-sided view. The opposite argument was always "they don't treat me as well as they can" or something like that, and so they excused their own behavior... And I get it now.
I have no doubt that there are many garbage collectors who find their job rewarding... But I've also no doubt that there are many who just do it for the money, and would be just as happy (or more so) if their needs were met by society and they could concentrate on something they enjoyed instead.
FWIW, I think it's important that people do things that they feel contribute to society. But that doesn't have to be "work".
