The affordable care act provides for free preventive services starting around Sept 2010. It will probably save insurance companies a bundle of money too.

Nothing is 'free'. Someone pays for it. If not you, who? Me? Fuck that.
Your work pays for your employer provided healthcare. That's why your employer gives it to you.
In exchange for your work. If you had a job, you'd know that.
And your employer contracts with the insurance company as to what they will and wont cover.... If you had a job, you would know that.
