President Lie About Obamacare Costs?

Did President Obama mislead the nation on the costs to government for 'Obamacare'. Indeed it appears to be so.

Yesterday (12/02/2013) The New York Times reported , "Over the next few years, the government is expected to spend billions of dollars less than originally projected on the law, analysts said, with both the Medicaid expansion and the subsidies for private insurance plans ending up less expensive than anticipated....

...Already, the Congressional Budget Office has quietly erased hundreds of billions of dollars from its projections. It now estimates that Medicare spending in 2020 will be $137 billion lower than it thought in 2010, a drop of 15 percent; Medicaid spending will be $85 billion, or 16 percent, lower; and private health insurance premiums are expected to be about 9 percent lower."

On the other side of the coin.
This past Sunday (12/01/2013) Rick Santorum, both a former Senator and presidential candidate, said on CNN’s “State of the Union” , "...the folks who are going to get into these exchanges are going to be probably sicker, older, and as a result, premiums are even going to go higher."

Isn't that what the GOP wanted?
That people should be more responsible for themselves and less dependant on government..

There can be no disagreement the same number of people will become sick whether they have insurance or not. There's only 3 ways to pay the costs. Either (1) people purchase their own medical coverage. (2) Government helps pays for some or all. (3) Medical costs are passed on to others by those who don't or won't pay their medical bills. This is entire argument is over who pays? As sure as the day is long, somebody's going to end up paying. These people aren't going to stop being sick.

Which would guys in the GOP like Rick Santorum prefer? (2) & (3) where everybody ends up paying either through government or additional raised premiums because of those that don't or won't. I would think the answer should be obvious.

Nobody expects the government or other people to pay life insurance, car insurance nor renters/homeowners insurance for another individual. Why, when it comes to healthcare should this be any different?
