When I go shopping for example apples are quite expensive compared to a bag of frozen French fries. Lettuce is also very expensive. We could change this with smarter subsidies.
Regarding corn syrup being put into everything, this seems to be a much more general health issue than for the poor alone. Obesity in the US is an epidemic that is much more widespread than amongst just the poor.
I agree that this means that surely we are doing something very wrong in this country!
I have the time to spend an hour feeding myself dinner every day, plus the time for the other meals. Not a lot of people do, however.
If you are working two jobs and have to make two shifts in a day, it's a lot easier to just grab food from the McDonalds you were passing by anyway, cram a handful into your mouth on your way home, drop a happy meal in front of the kids before changing out then in to your uniform, and heading to the next job across town, especially if the bus is slow.
