The problem here is insurance.
It cannot be cheaper for someone else to pay your bills for you.
Secondarily, there is the problem of someone else paying for the insurance which shouldn't be there in the first place.
So not only is someone else paying your bills, someone else is paying someone else to pay your bills.
With freedom liberty comes responsibility.
Refuse the responsibility, lose the liberty.
In the end,it doesn't matter who you give that responsibility to, government or business. The result is inevitable:
Liberty lost.
End of story.
The information will be used, not to discern whether the actuarial factors taken as a reason to charge more are mitigated by either personal behaviour or genetics, but applied to the gross statistics which were intended to find out who to charge more (not to give "discounts").
But beneath it all lies the question of 'Who owns you?" Do you? Does the Government? Your employer?
There can be only one answer it there is to be Liberty.
The only time I asked the Government to pick up the tab for my health care, they refused. Now, they want to force me to take it or pay not to. That's wrong.
I'm self-employed, for what that's worth at the present, that leaves it on me to decide what health insurance or care I will offer me.
Again, the government can keep out. If they fine my employer, they fine me. They attack the fundamental building block of small business, where the fundamental innovations and discoveries have been made that brought us most of the way here. That path leads to stagnation, the death of a Capitalistic system.
Leave health care decisions up to the employee...before some jackass in HR or HS&E is telling some guy who works on the shop floor on his feet all day that he has to go spend 30 minutes on a treadmill after work.
