Insurance prices are up because there are laws that prohibit hospitals from turning out patients who have no insurance or means to pay, so through higher costs we pay anyway. So the argument goes nothing really changes under mandated healthcare. This is not true.
When you have a central body providing for your needs, it's only natural that that body will turn it's attention to how you are using those needs. When it deems your actions detrimental and using up more resources than that body wishes to pay, it starts down that awful path of dictating lifestyles. From the get-go no and it sounds unreasonable, but its best to realize what sounds far-fetched is most likely what you are vulnerable to.
The other problem in our healthcare system is that it is now primarily a for-profit business. The biggest industry in the U.S. is healthcare. If business is booming, people are not brimming with health. When a things success is predicated on ill-health, how much do you think a healthy population is truly valued?
Yes, we may pay regardless, but we pay based on the market not a centralized legislation of law makers and politicians.
Take into great account what our government is now made up of. Prostitutes who no longer hide that they are available to the highest bidder. Obama, Romney, no difference what so ever. Link up the model of transforming our healthcare system to the systematic forcing down of charitable associations and driving up insurance rates, it sounds suspiciously like eliminating your competition and why shouldn't it? If you take into consideration the entire scope of observing our 'politicians' with all the warts, lies and contradictions we wink at, because we'd rather not think of the alternative, does it really seem wise to hand these people the keys to our lives?
There are better ways to handle this mess and it isn't taking the first well-worded option from a highly trained suit of clothes.
