In a fairly liberal area of PA I saw a manager of a Walgreens very aggressively (not physically) confront a shoplifter and yell out to never come to the store again. The punk tried to respond, but ultimately cowered to the anger of the manager.

I think that'd be unlikely - there was a massive evolutionary benefit for the plant to produce the amount of carbohydrate stores that the plant naturally makes. If it'd been more beneficial to produce more carbs, the plant would already.

I think a more likely question is what about nutrient density? Making more carbs, in a sense, is easy. Sunlight + CO2 == carbs. Nutrients are more stringently limited by the mineral properties of the soil. This just shoves into our food more calories we don't need diluting the nutrients we do.

Unless their plan is to make cheap, tasteless, vodka and sake
