That would be incorrect. The politics behind the policy of government meat inspection is really interesting, you should look into it sometime. Chicago became the home of larger, more efficient, meat packers were displacing local slaughterhouses all across the country. The smaller, local, businesses tried to frighten people away from the larger chains with lower prices by claiming they used diseased cattle, even though there was no evidence that this was occurring. These spurious charges threatened to destroy the market, both domestically and the burgeoning export market.
Then we have the cattleman who were overproducing, and driving down prices as a result. They, being the type where everything was someone else's fault, blamed the meatpacking industry in Chicago, and saw meat inspection as a way to increase demand, so they threw their weight behind meat inspection. In fact, the Sherman Act came out of the same political climate, even though no monopoly has ever existed unless it was backed by force of government.
In other words, this whole thing was nothing more than a bunch of non innovators objecting to market forces beyond their control, and demanding that the government step in to save them from progress.
