I manage a health plan for our smallish business of 19 employees. We offer "pretty good" health insurance, meaning, we pay around $600 per employee per month for health and dental. It gets worse every year. I am considering moving toward a HSA based plan, because upon analysis, it's actually probably better for everyone involved. The max out of pocket per year is the same, but instead of a $1000 deductible you have a $5k deductible. This works for our business (and I am assuming a bunch of other tech businesses) because our employees are generally young and in good health. It's a cheaper plan, the worst case scenario for an employee is the same, and I can give raises for the difference in price, and once every few years someone will need more than a $1k deductible, but the raise from the last couple years greatly exceeds the one time cost.
Anyway, just trying to frame my logic here, because I don't consider myself an evil employer trying to skimp on health insurance for my employees (which many I consider friends), but an employer that has to approve health plan changes annually which each increase cost by a considerable amount. If this trend continues, each employee will cost $900 a month within 5 years, and the coverage will be half as good. That's $5k a year per employee that I could put into their salaries, while not screwing anyone over on the worst case scenario.
