Take a gander at this New York Times
article regarding the ban of bake sales in the NYC school system. In a "nutshell", NYC school kids are too fat and the bake sales used to raise money for whatever cause exacerbates (it appears) the problem.
The number one cause for obesity is corporate America. They are forever finding new ways (and reinventing the old) to take money out of ones wallet by glossing over the facts and apparent need for their goods. Case in point, the vending machines in the schools. It provides another venue for merchandisers to sell their goods and for the venue to make some money themselves. You see, the school also profits from having the vending machines. The only loser is the person that uses the machine. But who the hell cares? It's all about profit, is it not? Profit now, ask questions later. Keep in mind that the only reason that the unscrupulous corporate greed mongers survive is because of moronic consumers. Not much different than the brain dead Jerry Springer crowd buying into that trailer park, low life insanity. Score one for corporate America. They found a population segment that spells huge advertising revenue. Hell, forget about the value of the offering, again we're talking profits and profits out weigh the negative impacts on society.
Anyway, back to school. The vending machine debacle. When I was in grade school we had a vending machine in the hall. It sold, believe it or not....APPLES! That's it. Nothing more, nothing less. In grade school we also had what was called a milk program. For 25 cents (or whatever it was) their was a 5-10 minute break and little cartons of milk were distributed and you also got a handful of raisins. In high school, there were no vending machines. You had lunch and that was that. Of course, you could always bring something from home and stick it in your locker and eat it between periods. School back then was not a market venue for profits. It was to learn. But that has all changed and the results are being seen with 20/20 hindsight. Congratulations to the visionaries who leaped on board to the corporate ship of profits for the sake of all else.
A Twinkie as a kid to me was a treat, not a right.
