You're right. The whole thing is security theatre at its finest. That's been true for years. Does anybody really think that an old ladies sewing needles are a threat to the airplane?
Of course they are, they could knit an Afghan... thanks, I'll be here all night.
Are you f'n serious? Keep bullied kids back a year and further bully them ("The System" bullies them by keeping them back a year), encouraging more bullying (the bullies are now armed with, "dumb dumb just got kept back a year") and docking them one year of pay (they now lose out on one year's income potential before retirement)?
Fix the problem: punish the bullies and the teachers and parents that turn a blind eye to them.
Makes perfect sense to me. As a kid I was a year ahead, academically I could hack it, but socially and physically I couldn't, so I got bullied. I didn't realize until many years later that the age difference was significant! I now think that if I had been kept back with my age peers I would have been much better adjusted, but at the time I felt there were failings in me that were causing me to be bullied... a few years of that and even my grades suffered.
