I personally wouldn't, mostly because I don't make enough money. If I break an arm, get the flu, or need some blood tests, I'm sure I can cover that bill, but I think about Mom's cancer. I'm quite certain that her three cancers spanning the last 30 years would have cost WAY more than their relatively ample purses could have held. Just one of the pills she takes retails for $16k for a one-month course. Multiply that by the 5 years she's been on it and you're at almost $1M. Her only option would have been to just let the cancer win and she would have died years ago.
Dad's knee replacement would have been $40k
My steroid injection last year would have been $1800, but with insurance it was $65
Carpal tunnel correction surgery that my sister just had would have been about $5000.
I'm not going to kid myself... I know that insurance companies are in the business of profiting and I know that they succeed very well at that, but I don't ever want to be faced with the choice of letting myself die or live in crippling pain the rest of my life because I had to make a financial decision. I don't want to be in an emergency room after a drunk driver put a fender through my kidney and say "which is worse - letting it fester and I die, or living the rest of my life in financial ruin in a cardboard box?"
I promise this isn't political, but healthcare costs in the U.S. are insane. Our average expenses on medical care (not even including what we pay on insurance) are nearly double the next closest country, and more than double the global average. Add in the average cost for insurance (about $8500/yr) and we're more than triple the next closest country in healthcare costs. We're ranked 37th in healthcare by the WHO. I would think for the money we pay, we'd be better than 47th in life expectancy. Even if I self-paid for insurance, that's an average of $700. 7 clams a month so that I can see a doctor for $15 when I have a tummy ache is better (for me) than choosing to NOT pay $150 for a visit for a tummy ache only to find out a year later that it was a baseball-sized malignant tumor in my intestine which will now cost me $750k.
Again, I'll reiterate.... this is my personal opinion for myself. I'm only offering how my mind sees it and how I've chosen. For me, it's not about how my healthy life has been in the past, it's for that possibility of getting run over by a dump truck tomorrow, my car falling off the lift on my legs, or other things you can't predict. I'm quite certain that I could have afforded and maybe even broke even on my healthcare costs up to this point in my life if I didn't have insurance, but it's the stuff you can't predict that will put you in trouble.
Let me put it this way.... if I'm laying on my deathbed at 104 after never having a major injury or illness in my whole life, I won't be adding up my insurance costs for the last century to see if I broke even.
