I don’t personally dislike Millennials. And I don’t blame them for anything. Like all kids, they are products of their parents, time and culture.
Of course the parents are at the root of the problem, but schools are where the real damage is one. The public school system has become the biggest babysitting business in history. Most of my freshman English students, even the bright ones, were quasi-literate at best. Nothing changes in college, where now you have quasi-literate professors teaching (indoctrinating) appallingly ignorant students. There is no bottom.
As for their personalities, I could suggest all sorts of crotchety old, white guy things about what might toughen them up. That’s pointless. At some time, they will probably face real adversity without their parents being there to bail them out. They will get tough or they will crumble. Life weeds out the weak, like it or not.
The world they will live in is beyond my imagining. They will adapt to it and thrive or they won’t and will wilt. Let’s just hope there is still a world left for them to live in when they come into their own.
