Not only is there a cure for cancer, but drug companies also spend millions of dollars to create new and better drugs for causing diseases like cancer. Some drugs are also put into our food (food additives). Personally, I think
this documentary is more interesting. It explains how the drug companies use drugs to make people sick (or sicker than the society has already made them), so that they can sell more drugs, to make more money.
Being mentally ill in a sick society is often just a healthy and normal reaction, so the ones who are sick are usually the ones who are healthy, before they are given drugs to feel miserably normal again.
It's not that doctors or drug companies are evil, it's just that money causes people to deceive and create problems to make more money. Like food additives, which causes the food to last longer or taste better, but gives diseases so that drug companies can sell more drugs. If there was no monetary profit to be gained from medicine, people would be more concerned about of each other than the size of their wallets.
The system of money has not only corrupted the medical industry of course, but most other things; even
science to some extent. Money is the primary goal in most things, people and
the earth are secondary.
