It's not the governments problem that nearly 70% of americans are obese or overweight... and the next generation may be worse.
Do you know what the government is and who it is supposed to work for and who it is supposed to represent? I'm just asking because it seems to me you don't understand what this entity "the government" is. It's supposed to be something that works for the public interest. And that means it should work on both the internal matters and the external matters.
But you know, fine, lets say you're right. This issue will continue and the USA will be the first nation in the history of the world to collapse from being too fat. You'll set a new precedent. Other nations collapsed due to environmental disasters, wars, famines (quite a lot really), diseases... america will be the first to fall flat on it's ass because it'll be too fat. Now it has a lot of junk in the trunk so it won't feel that painful but it's still gonna need one of those mopeds to waddle around the international stage. That's the future you want for america by not promoting healthy eating and a healthy life... and that's because you don't understand what the government is.
