Although I understand your point, there is a limit to the rate in which you can even spend cancer research money, even if you wanted to dramatically increase it. For one thing, you are limited to funding the research that you think will lead to a cure. It may turn out that the level of funding for direct cancer research is fine but what is needed is increased funding for nano-robotics or strong AI, or supercomputers that can simulate tumor growth and evolution. The linked article was very sobering indeed; finding a cure for cancer almost seems like trying to find a grand unified theory for physics. It may turn out that you basically have to figure out how to cure all diseases in order to cure cancer.
