In chapter 21, what new method or invention did the company owners implement?

And now the great owners and the companies invented a new method. A great owner bought a cannery. And when the peaches and the pears were ripe he cut the price of fruit below the cost of raising it. And as cannery owner he paid himself a low price for the fruit and kept the price of canned goods up and took his profit. And the little farmers who owned no canneries lost their farms, and they were taken by the great owners, the banks, and the companies who also owned the canneries. As time went on, there were fewer farms. ch 21
