Before the passage of the Affordable Care Act (Obamacare), my employer did not offer health insurance. My wife added me to her work policy for slightly more than $300 a month.
After the ACA passed, I was able to get health insurance through my workplace for less than $160 a month. I do have a higher deductible now, but even if I max my deductible every year, I will still save about $700 a year.
If Obamacare is repealed, I have no doubt that my employer will no longer offer health insurance.
