Human brains haven't changed. We have the same ability to learn, create and build as we have always had, what has changed is what is being taught. If history isn't being taught history won't be learned, etc., etc.. The blame is on the educator not the student. So that begs the question, why has the curriculum changed?
I agree the education system is a shambles. But that doesn't explain everything. Students, past a certain age, share some responsibility in their education thru their willingness to learn.
I just thank god that everyone on this board is perfect, knows everything and never gets anything wrong and definitely doesn't ever have editors pick them and pick footage that is designed to show the worst side to get views and reactions.
