This really shouldn't be considered profound or prescient, but the entire concept of of "free market competition" only works as intended if the customers actually shop around and compare their options. If people just ignore changes in the offerings available and stick with what they have regardless of the new options available, the "competition = better value" mantra collapses.
That's why I've been stressing the importance of shopping around on the ACA exchanges (or even off-exchange) so much this year. As I noted back in October:
Premiums are slated to rise steeply next year for health plans across the board. Yet almost half of voters who have health coverage under Obamacare say they will keep their current plan through 2016, according to a new Morning Consult online poll.
The findings could be a worrying sign for the Obama administration, which is urging people who buy their insurance on state or federal exchanges to shop around for new plans to avoid premium increases. But the results could also be seen as a positive sign for Obamacare, generally. Half of enrollees are satisfied with their current plan and another one-third are comfortable enough with the online exchanges to look for cheaper coverage, as intended.
