All money for agricultural extension, land grant universities has been toward developing industrial food. Lots of money has been invested toward maximizing yield. If you took even a small amount of that money and put it toward organic research, I don't have any doubts you could match those yields.

There are people who don't have the money to invest in better food, but perhaps they have the time. There's a trade-off: The more time you're willing to put into food preparation, the less money you have to spend.
