All this complaining is expected, but largely unwarranted IMHO. Healthcare is expensive--because it insures against a very expensive potential liability. It seems the system is working quite well for me (albeit because I am relatively healthy--not so well for others with ongoing medical problems, I'm sure.)
In any case, in California the premium increases are relatively small for my Bronze HMO plan. These are my monthly actual premiums (unsubsidized) for the past three years and for 2017 (at age 56). Not so bad, I think:
2014 $497
2015 $466
2016 $497
2017 $550
Once FIRED and eligible for the subsidy, I can make these monthly expenses ZERO!
