Unfortunately, most people have no idea how much their healthcare actually costs, and when they find out they are overwhelmed.
You used the term "healthcare", but you seem to be talking about "health insurance", as most employers don't pay for healthcare; they pay for insurance.
It's not like it's hard to figure out the costs. Every company I have ever worked for periodically sends a letter to employees telling them all about all the hidden costs the company bears. I have a company-subsidized health insurance plan. My contribution towards the premium is about $350/month. My company's contribution is about $600/month, making the total premium around $950/month.
The "Covered California" policy offering the closest coverage to the plan I currently have, costs over $1800/month. And by the way, "closest" isn't very close; the deductible, co-insurance, and co-pay are all significantly higher. On top of that, the doctor my wife and I have been seeing for the past 12 years doesn't belong to any of the ACA marketplace plans. I discussed this with him a month ago during my annual physical, and he told me that the reimbursement rates for the ACA plans were set at 60% of Medicare rates, making it a money-losing proposition. This is one of the reasons there aren't very many doctors and hospitals participating.
