Obamacare is racking up expenses, in particular, with the creation of insurance exchanges. In this video, David Williamson looks at this feature of Obamacare, and a possible free market solution. The problem is that these exchanges are proving more expensive than originally thought, up to an estimated $5.7 billion for 2014. No wonder less than half of the states in the country have come on board. One solution is an online insurance exchange. A form of such an exchange already exists. Will it work for a nationwide insurance market? Hard to say. On the one hand, it could offer small businesses unprecedented access to insurance plans. On the other hand, an online market may simply offer those plans with the best commissions and not the best deals. (EHTH -1.72%)
