As with many things, a high deductible plan makes sense in
theory and does not work very well for the average person in reality.
To walk through some but by no means all of the problems:
- The average person is bad with money. Always has been, likely always will be. A high deductible plan only "works" if you hold onto the money you would have spent on higher upfront premiums so that you can directly pay for care if you turn out to need it. The problem is, the average person lives paycheck to paycheck, saw the extra money in their bank account, and spent it. Now they're reluctant to get any care, even when necessary, because they don't have the money and it looks like a new expense. Which leads to worse health outcomes, and more things being put off until they become expensive emergencies.
- Few people have the medical knowledge to determine what tests are unnecessary or what procedures are marginally useful. Most people are not in the habit of challenging people who are the experts in the field, who they explicitly went to see for their knowledge.
- Even fewer people have that medical knowledge and have the time and energy to spend on navigating near-incomprehensible bureaucracies to actually compare prices, quality of care, etc to try to make an optimal choice.
-----------------
The solution to expensive healthcare should not be that everyone needs to become financially disciplined, a domain expert in healthcare willing to challenge authority figures, and to waste large amounts of their own time attempting to provider-shop in a system unlikely to ever make that a simple process.
I have a HDHP. I save a bunch of money with it, and unlike the average person, I'm in a position where I can do all those things. I get a relatively optimal outcome, although it still wastes a bunch of my time to navigate.
While I personally benefit, I strongly feel that HDHP's are not proving to be a net-positive for the system or society.
Here's a recent Bloomberg article basically going through a bunch of those unintended consequences: https://www.bloomberg.com/news/features/2018-06-26/sky-high-...
