Doesn’t explain it. People value their kids future over anything else. A parent knows this. No amount of money can corrupt that. 

Either they were compromised and are being puppets without any means of not doing as they are told, or they actually believe the things they do and say (less likely imo). 

 Not all parents put their children’s needs ahead of their own 

 Hard to imagine, unless they are psychos. 

 Sociopaths is more likely  

 More than a few are clinically both.
