Well, I don't believe the full law even kicks in until 2014, so those saying their healthcare costs have already gone up, you're going to have to show me it's a result of the law and not just from the normal rise of health insurance costs which happens on a regular basis. Also, if health insurance companies stand to lose money over the law, it's likely they will raise, or have raised, costs to stick it to you one last time while they can. So, should you be mad at the law or the company bending you over?
I don't know if the law will stand or not, but the arguments against it are pretty ignorant.
1) As far as the mandate is concerned, if the government can't make you pay for anything, social security has to get struck down too.
2) This idea that it's going to make you pay for other people's health care is idiotic. What do you think you've been doing this whole time? Why do you think your premiums go up? Certain things are constant (a) Everyone at some point in time goes through the healthcare system. (b) Doctors don't turn people away that have hatchet wounds in their head. So they will use their time and resources to patch that person up (up to a limit) (c) If they don't pay, those currently paying for health insurance get the bill passed to them. The mandate makes it so that the guy with the hatchet wound in his head has to pay prior to that incident so the cost doesn't get passed on to you. This increases the pool of money and hopefully slows down any future cost increases. This is the exact OPPOSITE of making you pay for others.
3) You pay taxes which pays for your local police whether you call them for any reason or not. It makes more sense and is much safer to have them in place than not. Someone has to explain to me why someone running to the police saying "help me! help me! this guy is gonna kill me!" is different than someone running to a doctor saying "help me! help me! this cancer is gonna kill me!"
