The problem is demographics. There are just too many Baby Boomers entering their 70s who are going to be needing a disproportionate amount of health care due to their age. They all vote and they all want pre-existing conditions covered.
I agree about the demographics, but Baby Boomers in their 70s aren’t the real problem here. At least they qualify for Medicare. The real problem is people in the 45-65 age group who have lost their jobs and are forced to buy very expensive insurance when they can least afford it.
