Who are you, random internet weirdo, to indict seven billion people because of a company making and selling a drug. For a cranky libertarian hermit you sure have a lot to say about how the market is wrong.
When they have a similar solution for helping tamp down on severe alcoholism, I look forward to your equally ludicrous opinion about "people spending too much on alcohol" and "getting intake under control".
You couldn't even be bothered to cite one article that would prove spending more money is correlated with obesity. Luckily for me I have plenty that prove your claim is ridiculous on its face.
