I just can't not on this one as the logic is so insane.
So the premise is a 30 year old parent gives his 5 year old a participation trophy and that's the 5 year old's fault.
The adult makes a choice here. The adult had issues with their parents, or was so weak they couldn't deal with their kids disappointment or whatever.
5 year old's aren't calling up and ordering themselves trophies.
The only person at blame is the parent. Now is it possible that parenting strategy led to some shitty people... absolutely.
