I think some of you really need to rethink this. Individual exchange business under ACA is a financial drain. Sure, these companies are making a profit but that is coming from other sources (Medicare, Commercial, Specialty/Ancillary - think dental, life, disability) and not these members.
Last year (as it was one of the companies mentioned) Humana spent more on claims than they collected in premiums for these plans to the tune of a couple hundred million dollars and had to dip into their reserves (Google it).
The simple premise of ACA from a financial/profit standpoint is bogus for these companies. Everyone is eligible to get coverage, but it the majority of applicants are unhealthy/have medical conditions while the healthy people don't sign up for coverage and/or take the penalty it's pretty obvious what happens.
Get the heck out of here with the "they are just doing this because they were slighted" bs.
Aetna fully supported ACA until their merger was blocked. Maybe that was a huge coincidence (lol)
