‘You need to think this through....’
it’s probably true that a cure is not being purposely hidden, but it is completely true that costs, in terms of chemo and others, are artificially inflated by the mixed cocktails that are given, such as Taxol and some carboplaten...these combos are called therapy regimens, and are standard treatment in US...
If I am understanding your point it is that the wealthy and affluent receive better treatment than the rest of humanity.
This is likely true. The world is not fair. But consider the healthcare the average American receives who has no insurance and shows up at the ER. It is far beyond what the majority of the world receives.
The best guarantee of good health care, a good standard of living, and a clean environment is a wealthy and prosperous society. Therefore, based on logic, the best solution to the ills of the world is free markets and capitalism. It makes life better for everyone even if it never attains equal outcomes for all.
