It's not much different in farming.Red Steagall used to occasionally use this quote on his radio show:
Cattle ranchers and farmers are the only ones in the business world who buy retail, sell wholesale, and pay the freight both ways.
-- R. Lewis Bowman
Technically you have to buy from seed dealers, and put in writing you won't use their seed to reseed the next year forcing you to use them again. Ten zillion varieties of seed guaranteed to produce a record crop without rain during the growing season or survive under flood waters.
Then you have idiots like Governor Cuomo from NY on national TV saying he could be a farmer. Just stick a seed in the ground and harvest it when it's ready.
No big deal right?
Fawking idiots.
