Here is how the current healthcare bill will achieve this:
The government will mandat and control the pricing of insurance premiums (actually the government is already largely responsible for the price of insurance premiums being so high today) - the average premium for a family will be $15,000 per year. If you can't afford that, then you jsut pay a fine to the IRS every year. The are hiring 12,000 new IRS agents to handle the enforcement.
Then when you get sick or have an accident, you can buy an insurance policy. The insurance company will be prohibited from denying you because of that pre-existing condition. It's like buying a homeowner's policy when your home is already on fire. The insurance company cannot stay in business if it can't take in sufficient premiums, and is only paying out claims. So the insurance companies will be forced out of business.
The other way the insurance companies will be forced out of business is that Employers are going to incentivized to drop their employee health plans because it will be cheaper for them to just pay the fine to the IRS every year, instead of the paying the ever increasing insurance premiums that the insurance companies will have to charge just to stay in business in this new Government-forced environment. If more and more Employers drop their employee insurance plans, that's less and less premiums for the insurance companies - it's a vicious cycle - they have to raise their premiums to stay in business - making it even more unaffordable for Employers to pay the premiums, and thus making the decision to drop the plans and just pay the fine to the IRS.
Obama has said over and over (on tape) that he wants a Single Payer Government plan. This healthcare bill is designed to achieve that.
It's nothing short of Tyranny.
