Consumer demand driving the food industry

I have no doubt that the increase in consumer demand since the 50's has played a key part in changing the food industry dramatically. From an economic standpoint, it is quite logical. The more food that the consumers demand, the more food that these companies need to produce. It was only a matter of time until some of these companies realized that by corporatizing the industry, more profit could be raked in. Cutting corners during production and development of livestock isn't really that much of a shocker, considering how greedy these corporations can be. It's immoral, the things they do to these livestock before they are sent to the slaughterhouses, just so they can profit. Now you can't blame the consumers for demanding more product, they're sold something they like, but they aren't shown these atrocities. Now finally activists are taking a stand, but it's too late. People are already used to frozen meals, fast food, and pop as part of their daily routine. The consumer demanded more and the food industry took the chance, ran with it, and cleverly covered their tracks, with no concern for public health at all.
