I feel like this could have to do with factors other than just wealth. It also appears to be a retrospective analysis that doesn't usually separate the cause and effect. Survival rates always tend to be higher in patients with more disposable income. Some of the reasons are socioeconomic and not purely economic. There are many factors that change your place on the lists and also change the survival rate of an individual including compliance with prescribed treatment and comorbidities such as other systemic diseases that can effect outcome. Sadly lower socioeconomic classes have higher rates of both these complicating factors. My experience says that even if the money is provided, and everyone went on every list, you would still see a separation in survival in these groups. Is it fair? No. Can that be fixed? Unlikely. You will always see higher rates of fast food and other vices such as smoking in lower socioeconomic classes and lower survival rates due to any disease. You can't force people in a free society to do anything they don't wish to, including taking care of themselves.
