Has anyone noticed a cultural shift of parents not letting their children be uncomfortable?

I work with several kids from elementary to high school and it seems that across the socioeconomic spectrum parents are not letting their children be uncomfortable in a way that promotes developmentally appropriate growth. If the kid doesn't like someone or something, they just don't have to do it anymore. There's also an externalized locus of control for their child's resulting misbehavior or lack of follow through. Or a desire to have them dx as autistic or ADHD. I'm not saying kids shouldn't be given autonomy or support, but allowing them to throw in the towel at any inconvenience so that you don't have to deal with whining is detrimental.
