I know that that growers are very smart and generally make the choices that increase their incomes. Given that Monsanto's seeds cost more money, growers must make more money through yields to pay for them. A few may make the wrong choice, but not thousands. You would apparently have us believe that growers are fools. The fact is, monopolies are a hard way to make a profit.
Someone always comes along with a better product, or a higher bribe.
The easiest way to make money is a better product.
