Obama's statement that existing policies will be acceptable for Obamacare is simply not going to work

The insurance companies have spent 2 years rewriting their IT systems in preparation for Obamacare. 
They are not going to be able to change them back again in 30 days. 

Many of the cancellation notices have already gone out or are in the pipeline. 

The Insurance companies are not going to pass up the opportunity of canceling unprofitable plans and the opportunity of issuing higher priced and more profitable plans. 

Many of the smaller players have already decided to withdraw from the market in many States as the costs of Obamacare implementation was too high. 

In many States ,Obamacare has created a de facto Health Insurance cartel with only a few players. 
This will further erode competition and increase the price of Health Insurance even more in the future. 

In many ways Obamacare is making Health Insurance more like the scam that is loan / credit card payment protection insurance, which was a cash cow for the banks and the insurance companies and was linked with a whole heap of mis-selling scandals. 

Obamacare makes the Health Insurance market even less like the Motor Insurance industry. 
Motor Insurance is a highly competitive industry and pays out 100% of premiums in claims. 
The Motor Insurers actually reduce the cost of car repairs by doing hardball deals before including garages in their approved list of repairers.

Just over 4m cancellation notices have now been issued for people that previously had health insurance. 

A mere 100,000 have been enrolled in Obamacare. 
The government is trying to make the numbers look better than they are by including those who are being transferred from Medicare/Medicaid plans. 

So the nett effect of Obamacare so far is that 3.9 million FEWER people have Healthcare Insurance. 

It was known back in 2009/2010 that over 60% of existing Insurance plans would not meet the criteria that Obamacare dictates and that there would be many millions of cancellations.
But Obama went ahead anyway.

Obamacare increases the cost of Health Insurance (pre subsidy).
The real fun will start when business health insurance plans are included. 
Obama delayed the business fines because he knew the chaos it would cause and how many votes it would lose in the mid terms. 

Obamacare dramatically increases the profits of large health insurance and drugs companies. 

Obamacare is expected to cost $3.5tn+ and 800,000 jobs over 10 years. 
It will lower future GDP growth, raise unemployment, lower tax revenues and significantly increase the budget deficit and National Debt. 

There are a great many ways of improving American Healthcare and broadening coverage. 
Obamacare is the worst scheme anyone has come up with so far.

The first thing that should be done is to halve the cost of Healthcare.
