12 - 13% of the population are responsible for most of the healthcare costs in the nation. That is why insurance companies post huge profits because their most members are relatively healthy.
You pointed out an emerging problem because that percentage is fixing to get more robust and Medicaid is fixing to get submerged soon.
1. I agree with your first premise.
2. I don't understand the second one. How is that 12-13% of the population "fixing to get more robust...."??
1964 marked the END of the Baby Boomer population so when THAT group is done the population will become stable again.
