There have been huge advances in, for one, breast cancer treatment over the last 15-20 years.
When you say "for what?" I can only point to the aggressive variant of BC my wife was diagnosed with 3 years ago. A death sentence literally a few years ago, she is now recovered and has good prospects for a long and productive life.
This is only possible because of the "fortune" of research thrown at her particular form of cancer in recent years; but it goes deeper than that. Because of the expense of the (relatively new) treatment and limited history of efficacy/results, her specialist had to personally argue the case for her to receive the treatment with our local health authority (I am in the UK btw so perhaps this is different to the US).
As more women (hopefully) successfully recover with the use of this treatment, resistance to spend on research will hopefully fade in the face of such positive results.
From the brightest cancer researchers in the world down to the people working in your local chemotherapy unit, progress is being made at a better rate than ever before. It's just very hard work, and I don't think money and fame really come into it - there are easier ways to achieve that:)
