While at the Watson-Crick Institute, Crake shares a secret with Jimmy. He talks about how Health Wyzer creates medication to cure people, but also things so they never have to be sick in the first place. To the citizens taking the drugs, this sounds wonderful, but because Health Wyzer is a business first, they cannot have this.
If no one gets sick anymore, there is no need to buy any medication, so Health Wyzer is out of business. This is where vertical integration comes in. Health Wyzer is not just inventing new medication, but also new diseases that they plant in their medication so there is an endless cycle of profit.
When Crake is explaining this concept, he says, "The best diseases, from a business point of view, would be those that cause lingering illness. Ideally—that is, for maximum profit—the patient should either get well or die just before all of his or her money runs out. It's fine calculation." (Atwood 256). This stood out to me because it seems like Crake thinks it's more genius then evil.
This could just be Crake covering up his feeling though, because he does explain how his father died because he knew about Health Wyzer's plans. His father added up all the information, but before he could tell anyone, he 'fell' over a bridge.
I find it ironic how Health Wyzer would do this to innocent people because they have such high faith in Health Wyzer to make them better, when what they are actually doing is making them more sick. Health Wyzer's sole purpose is to produce medication; to heal, but all they care about is making money.
This could be a reason why the world is like what it is like for Snowman. People could have found out about Health Wyzer's secret and riots could have broke loose. Since Jimmy already knew, he could have avoided them and hid somewhere and that is why he is still alive.
Connection: I connected this section to an episode of 30 Rock called "Let's Stay Together," because they talk about vertical integration and that is why I know what it means.
