Obamacare was designed to fail, but to do so in a way that it destroys the insurance market for healthcare. This will leave single payer as the only viable option. The fines are so low to encourage people not to sign up for care. There is no other logical explanation. If they wanted you to sign up, the fine would be larger than the price of the insurance. This will create a death spiral where the only people signing up on the exchanges will be people who have high medical costs. Healthy people will avoid the exchanges and pay a fee. Companies are already dumping or limiting insurance coverage putting millions more people into this completely unworkable system. Remember, the government is only setting up the exchanges; it is insurance companies signing people up. They can't charge more for people who will cost more. Those costs must be distributed to the healthy and the young. Insurance companies cannot stay in business if they can't attract enough healthy and young people to offset the high cost of people with prior conditions..
The only flaw in the plan is that the abject failure of the website is making people doubt the ability of the federal government to pull off something as critical and vital as running healthcare. But it does not matter to the democrats. They want single payer.
