the communist in me yearns to blame capitalism for everything, and its sort of their fault but not directly, the actual reason that nutritional content is going down is because plants are growing faster and bigger while taking a similar amount of nutrients because there is more co2 in the air, its not really about business pressures or anything to do with specific decisions being made by corporations or farmers and the difference is irrelevant anyways (for now).

But it does boil down to business pressures. The business prefers more and bigger produce to more nutritional produce.
Is that a bad thing? Maybe not. Maybe you can just eat more to get your nutrition since higher yield should reduce cost.
But the point still stands that there is very little business pressure to make a nutritious product.
