Quote from article: "Many families, especially poor ones, get a whole lot for their hard-to-earn dollars when they buy cheap, processed and calorie-dense foods. Fresh fruits and vegetables are more expensive, don't last as long and take time to prepare -- time that's hard to find if both parents work full time to pay the bills. This gap between the waistlines of the rich, middle class and poor is only going to get worse with rising food prices"
Good Doctor, this is the root of the problem. It's too expensive to eat well. Many of us don't have a Whole Foods, Wild Oats, or similar store, and at minimum wage or slightly better, nobody can afford to buy "good" food. Kudos to you for acknowledging this fact.
People need to use birth control too. Look at the explosion of children and the lack of thought given as to how much it costs to raise one.
