Never has an OP so annoyed me. Ignorant, rude and completely thoughtless.
Not only is it completely unfeasible to expect people who are feeding themselves on a shoestring to spend a huge portion of their food budget on free range, organic (pah) food, the OP evidently has absolutely no idea of the main drivers in people who are living on the breadline.
Aside from the fact that they may only have about £20 to feed a family for a week (for instance). Some people do not have any access to transport. So if they live in a deprived area they cannot access the wonderful farmers markets or chi-chi little shops where free range eggs are £1.50 a dozen. They probably have to shop at Farm Foods or a similar food shop, where even battery eggs are expensive, and free range ones are prohibitive. As for meat, they probably wouldn't have a selection, like your local Waitrose, of cheap organic cuts of meat, they would probably have Danish bacon, cheap chicken drumsticks, possibly battery chicken breasts (which would costs a fortune anyway) and crappy sausages. Whatever is on offer anyway would be far more expensive than a frozen pizza, anyway.
There is a very rigid 2-tier food system in this country. Comfortably off, middle class educated people eat organic and free range and ethically sourced foods and are praised. The poor eat the mass-produced crap that is within their budget and are ostracised for having to do so.
The media doesn't hugely help, I am thinking of the much hyped Jamie Oliver 'campaign', where we were encouraged to scoff at stupid people who fed their children kebabs.
