Sure I can. We don't have a cure.
See?
We also don't have a cure for the flu. Or for the approximately 300 types of "common cold." Or for aging. Just treatments. That's all we have. Sometimes the treatments work; sometimes they don't.
The fact is, if doctors CURE you each time you get sick, they can collect money from you over and over. If they let you die, they only get money from you once. You tell me which one makes more sense from a profiteering perspective.
Dead Customers = Lost Business, Nemo.
We'll get the various cancers figured out. It may take a while, but it will happen eventually. In fact, even today, cancer is usually survivable. Sometimes it's not, but it's a horrendously complicated disease. The difficulty in not harming the patient while treating something that has spread to cells throughout his entire body shouldn't come as such a surprise.
I'll tell you what DOES surprise me - is the difficult doctors have with heart disease. For crying out loud, dying of a failure in a PUMP? How absurd.
Scientists really need to work on developing artificial or cloned hearts, then get them implanted in people so that they have redundancy. The idea that millions of people still die from congestive heart failure - which usually provides years of advance warning - is mind boggling to me. The heart is just a stupid PUMP! We can't replace it?
Unbelievable.
If you want to advance a more believable conspiracy, take up that one. Heart disease is a far simpler ailment than cancer, and it kills even more people.
