As soon as people start hinting at conspiracy theories it's usually time to just nod and agree. As you can imagine, I didn't quiz my school librarian about the funding of her computer when I was 14 but let's just assume it was MI5 and leave it at that.
Sorry, you've just lost the argument. Marketing might be considered conspiratorial but that's a bit of a stretch. Try "profit" as the motive for sponsorhip and maybe we can try that one again.
I would disagree that it's desensitisation
OK, we'll have to differ there. The point I was trying to make is that if people do things as kids they question those same actions far less when they do them as adults. It's inevitable, not deliberate (if that's what you were hinting at).
I'm not quite sure how the pocket reference is at all relevant
Because a wallet or purse is not the only place that a card can be kept. There is also the option of keeping it in one's school-bag and taking it out (and putting it in said pocket) as needed.
Fingerprinting is an expensive way of doing something that can be done with a simple card - and a card has the additional benefit of helping kids learn not to lose things. If bullying or theft is the problem then that is what should be tackled, and properly - not just hidden by removing anything of possible value.
