This is both a classic situation and unfrtunately one that is also epidemic in all age brackets.
Now that universities have begun to operate as profit centers and students are customers buying the "education product" many of the small ones have opened their doors to anyone who can come up with the tuition (scholarship or parent's pockets). Of course you have to keep the customer satisfied and most important, keep them paying tuition. That inevitably means lowering standards. Good intentions pave the way to hell. Too many of the students I met before I retired (in fact, much the reason for my early retirement) were kids' whose awful behavior in class was disruptive of the classroom environment to the detriment of their fellow students ability to learn. I got tired of throwing miscreants out of my classroom. Unfortunately it doesn't take too many of such to sour the whole experience. Sound like an inner-city high school? This is at the UNIVERSITY Level! I still work with motivated students in the university''s honors program but it seems to me, on average, too many young people in recent generations appear beyond redemption. My conversations with secondary school teachers indicate essentially the same experience. The real problem with american education may be the enabling parent and their willing accomplices, the school administrator whose primary concern is protecting their precious six by placating parents who are as out of control as their children. Administrators who back up their teachers in the face of parental tyranny seem to have become rare. Invariably, parents have resorted to legal advocacy. The parental law suit has caused school administrators to become besieged. It's difficult to blame the administrators from operating with an eye to their school system budget. Most towns can't afford major litigation let alone settlements. I could go on and on with examples that would make your skin crawl.
This rant will no doubt receive much dissent. One should never criticise the right of an american parent to raise their perfect little monster in whatever sociopathic way they see fit. FDF, If I had imitated the behavior of the child you describe, I would have been unable to sit for weeks. If I had been thrown out of any class, I'd have to immigrate to the Amazon jungle to escape my parent's wrath and would never have been allowed to reenter the campus let alone the classroom. In the old days, there were consequences to such behavior. Sorry folks. needless to say, this account hit a nerve.
