Growing Your Own Food
You have to be paranoid beyond measure to believe that they (whoever they are) want you to be dependent on grocery stores.
That said, the only problem associated with learning how to grow your own food is that, because our school time is finite, this means taking time away from something else. What needs to go away? It’s usually algebra II.
That means no Americans can go to college, which means no more American doctors, lawyers, scientists, engineers, corporate executives, etc.
