Earlier quoted context omitted.
Yeah, I wouldn't consider any HDHP (High-Deductable Healthcare Plan) to be "good insurance".
It is when you take into account the tax advantages of an HSA. If you're like me and can shake off a few grand medical expense out of pocket, suddenly it's the best plan. I have a HDHP and paid less than $10k all year for my family's medical expenses and we had a freaking baby lol.
The minuscule tax advantage here is that 1. you're paying for your health care costs with pre-tax dollars, but you can generally still deduct these even without an HSA, so +0 advantage there, and 2. you are allowed to invest the savings, and gains are not taxed at the federal level (but may be taxed at the state level), so the advantage here is your savings account size x your effective tax rate. The premiums for a HDHP also tend to be slightly less than PPO or other plans.
For most of us that tax advantage is tiny. I would rather have an insurance plan that actually covered my costs minus a copay, even better one without a copay, even better Medicare For All where I don't even have to worry about an insurance company or pay insurance premiums. HDHP + HSA is pretty much the worst of the bunch.
