How much money do the health insurers invest?

I'm having trouble researching this. But I'm not all that smart.

It would seem to be a reasonable argument as to why big business is against government managed health care. To wit that health care insurers invest a lot of money in our system.

I've read that health insurers have a big investment in tobacco stocks. Which is interesting. But I was trying to get some idea of how much they have invested in toto.

And how much might become unavailable if the government would take over part of the health care.

I would think that this issue might be discussed more but then I thought maybe they don't want the average Joe to know how they operate. Which is : take your premium money and invest it to make even more money and hope you never come crying around to get some money back.

One would think that everyone already knows that but I'm not sure. I've talked to many people who were shocked to learn that the government spends their FICA payments as soon as they get it. One women I talked to couldn't believe that they weren't saving her money for her retirement.

This seems to be the "backbone"
