I have only one problem with this
Ever see that episode of southpark where walmart takes over... They kill walmart and start shopping at their local general store like crazy and it becomes a walmart like industry on its own from the growth
Thats exactly what would happen to those small farms atleast the ones who see a crazy sudden increase in profit.
Farmers gonna see a sudden increase in demand on product.. They are gonna adjust... and those humane as you call em ways of raising chickens will go out the door as they have to make room for 5x more chickens then normal.
Its just how we are as humans. We are fine as small time buisness. But when we see a sudden increase in demand and profit we adjust and things get worse.
