I see children bigger, taller and better fed than ever before.
I'm guessing you meant to say "more fed", rather than "better fed". There is no way that, as a whole, we are better fed than previous generations. Diabetes and obesity are at all time highs, and are spreading to less industrialized countries. And this is due to the quality (or lack thereof) of food that's being ingested. I think it all boils down to corn subsidies - corn subsidies are costing our country billions of dollars, in order to keep prices down so food manufacturers can continue to feed us cheap junk food and turn record profits.
I'd like to see us go in the opposite direction with farming subsidies - stop paying out to monoculture super farms that grow nutrient deficient "food" (you can't even eat the corn they grow!), and instead put all of that money into subsidizing localized organic farms. What this would achieve is:
1 - nutritious food at affordable prices
2 - increase the cost of foods that are causing harmful health effects, which would...
3 - increase the health of our population by reducing the amount of junk food we eat, which would...
4 - decrease the cost of health care
Other effects would include:
1 - strengthening local economies by keeping food production/sales local
2 - reducing emissions caused by shipping food long distances
3 - creating localized, rather than centralized (or mechanized), jobs
