Very true but how many people would pay the extra cost for vegetables outside the agricultural industrial complex? Most people want cheap and their fruits and vegetables year round, even if they are out of season. There is a major taste difference just between canned vegetables vs frozen.

My biggest annoyance is ordering a BLT in August and getting a green artificially ripened tomato even though ripe and flavorful ones can be found everywhere. You would think that CSAs would be a lot more popular and successful then they are but the reason (imo) is that most people really don't want to cook and even if they do, they don't want to do that every day so the CSA shares end up overwhelming them with fresh supplies that get given away or thrown out instead.
