The big consequences to employer-based health care have mostly been lit upon in the thread. First, because it’s subsidized, it’s a huge regressive tax break for the well-employed. It’s not even a “flat” tax cut, because wealthy people pay higher tax rates, so they’re saving more on any dollar that isn’t taxed.
Moreover, this leads to overutilization – I saw a speech last weekend with economist Jonathan Gruber, and he told a story about this. His kids’ braces cost, whatever, $26 a month. His employer decided to offer an optional orthodontia benefit at a cost of $30 a month – not worth it, it would seem. But because of the tax-advantaged status of health benefits, that $30 out of his gross paycheck every month only cost him $22 net. So he got the insurance to pay for the braces his kids already had. But once he wasn’t paying himself, why should he make value decisions? So they got every bell and whistle that orthodontic science had created. These weren’t worth the money. But he wasn’t the one paying the money, so he overutilized.
This is a big problem – because it’s cheaper for employers to deliver $1000 in health benefits than it is to deliver $1000 in cash, the system funnels a ton of money into health insurance. This tends to raise the price of insurance for both individuals and employer-sponsored group plans to make up for the discount. At the same time, not only is there overutilization as above, it depresses wages way down, but it does so invisibly.
Another issue discussed in the OP, which is completely true, is that it leads to a landlocked labor force, esp. w/r/t experienced workers who want to join a small business. Because of health care costs, esp. when pre-existing conditions are involved (which older, experienced workers are more likely to have), someone with health insurance is never going to switch to a job that doesn’t carry it. When any component of production can’t move efficiently, that makes things cost more – this is true of the labor force just as it is of cargo sitting on a dock.
A subset of this problem is that it retards entrepreneurship, because people who are skilled can’t comfortably leave their office job to start their own shop, as there’s practically no ability to get health insurance – esp. if there’s a preexisting condition in the family. I can’t find the cite right now, but the estimated loss of small business start-ups due to this reason shocked me in how huge it was. Since small businesses are job creators and centers for innovation, this is a massive, completely sub rosa drag on the economy.
