Man, we are like the same person on this topic. Everybody knows that people base their to get or not to get cancer decision on who pays for their medical care. If they know the government is going to pay for it all, they are happy to choose cancer cause they know someone else will foot the bill.
Make poor people pay for their own healthcare and the Laffer curve will show that not only do they stop choosing to get cancer, they live the rest of their lives without seeking medical care at all.
