Your company is passing the ever-increasing costs (which, again, have been on a steady sloped increase both before and after the ACA, since the 1970s; https://ourworldindata.org/grapher/health-expenditure-and-fi...) along to you, yes. This is a significant problem with our system; people think they get healthcare for $50/month, but it's really coming out of a reduced salary.
You're getting fucked (as am I!), but the ACA isn't what's doing it.
> The Affordable Care Act requires employers to report the cost of coverage under an employer-sponsored group health plan. Reporting the cost of health care coverage on the Form W-2 does not mean that the coverage is taxable. The value of the employer’s excludable contribution to health coverage continues to be excludable from an employee's income, and it is not taxable. This reporting is for informational purposes only and will provide employees useful and comparable consumer information on the cost of their health care coverage.
So, it went from "I pay $50/month for healthcare" to "my paycheck says they're taking $2k/month! what the fuck?!" in folks' minds.
