To the folks that say "2 generations" ago we were a farming community. Maybe. But let's not forget that cities have been around for thousands of years. Some of us DON'T have farming in our roots. One of my maternal great-grandfathers was a tailor in downtown LA (well, I guess, regular old LA at the time); I don't know farther back than him on that side. My paternal great-grandfather was a lawyer in Chicago.

Not exactly ripe with knowledge of "living off the land." Supposedly there's a farmhouse in Indiana somewhere that was linked to the family somehow, but lord knows how.

Can I grow a plant? Probably, but growing a few tomatoes or an apple tree is hardly enough to sustain me. Could I kill an animal? Again, probably. At least here I have some knowledge of anatomy and could probably butcher it - messy but edible. But I'm not gonna be the guy that's growing food - I'm the guy that barters my skills for it.
