Now let's assume Obamacare falls apart (even I can see it's not doing too well, from the enrollment numbers to the website to people losing plans to people's plans price rising)

How do you make sure that people with pre-existing conditions can get insurance? If you remove the mandate but leave that clause in, it will raise the price of insurance on all of us. 

Personally, I would go with a public option. That way, insurance companies can keep doing whatever they want to do, those who have pre-existing conditions can sign up for the option, and insurance companies would finally have decent competition.

For my Republican friends, please note that leaving it to the free market is not a good answer.

I just learned about Obamacare in my HSCI course, it will fail unless it evolves beyond what it is now.  There are so many flaws in it, Obama is trying to cater to the insurance companies and at the same time offer universal care.  That just won't work, the only way to offer universal care at an affordable price is to adopt a system like we have in Canada cause your administration costs are through the roof in America since you have to bill to all kinda of different insurance companies and everyone has different plans, in Canada every bill just goes straight to the government.  The Insurance companies just have way too much control and its screwing over all the American citizens. 

Then ....... I'm going to Canada.

Private insurers will get more money, from people trying to get back on their plans, now they'll have plenty of new conditions and hidden fees it's gonna be great for insurers

100,000 people have signed up in the first month. And 3 million have lost their insurance plans. Fucking joke.

Yep, it's not a good answer, it's the best answer. Unfortunately we haven't had a free-market in most of healthcare since the 50's. Just look at eye-care and its low-costs and you can see how a free-market (free from government priveleged insurance companies) can reduce prices and make something affordable.  

Then plans go up in price and down in coverage like they did every year before obamacare. Hospitals continue to rip off insurance companies and everyone gets more money in the health industry.

I shudder at the thought of a true "free-market". Insurance companies hiking up prices whenever they want, dropping people off insurance, refusing to cover medical treatments at a whim. 

The free-market you're talking about won't happen because there is simply not enough competition. In my area, we're almost monopolized with Blue Cross Blue Shield. Imagine if they were completely unregulated.

No in a free-market there would be competition and the market prices would not be arbitarily determined by doctors, as they are now. This is how the market worked pre-1950's and how the market works in certain areas now (optical care/dental.) There is no competition, because the government gives certain companies priveleges, such as tax-exemption and forces regulations that the smaller companies and practices cannot meet. Big hospitals control the healthcare system, and the ACA cements this big business model further. 

Then we go back to whatever people were doing before it. Getting cheap plans, saving and paying for medical coverage, piling up a huge medical debt that they may never pay off until they go bankcrupt, or going on State benefits while they can.

I bet if Obama Care were to fail most of the old policies would go back in place as well, which they have cut down on to save money. Adults have to pay for part of their prescriptions now, no fillings for Dental, hospital stays are not free, etc.

But we will survive. Only thing that will not survive is Obama's legacy, the only thing that had a chance of being a positive idea from him. Other than the Stimulus multi billion- trillion dollar package.....Which as not really that positive. Except for Banks and Auto industry.
