Thanks for your review!! The other part of that statement you quoted, btw was "they need more time to catch up to something that's older." Just in case you wanted to know.

edit:

You can feel free not to agree with some of my points but from a historical viewpoint-It's true.

What is the oldest food that man first ate? Before farming, before hunting. Fish! Everyone supposedly ate fish... (According to biblical times that is.) Fish is currently one of the most expensive foods. A swordfish steak, uncooked, can cost up to 20 dollars. Even the cheaper fish like pollock is at least 7 dollars for a box of small in size fillets, compared to 3 for a large pizza at my local grocery.

Edit Number two. Although beans may not be the most expensive food currently in flat raw number, price, it has risen greatly in percentage from its price decades ago compared to some other less popular foods, which are also more expensive but percentage wise not as much...

Edit number 3: Wow I wrote a lot. The last thing... usually Governments pay for part of the cost of necessary foods before you buy it, in a lot of countries actually... "Necessary" being the key word here, I don't mean chocolate. So it's sometimes a bit harder to notice the real price of some of the things you may buy at a grocery store.
