Perhaps you don't find 1k+/month to be a lot, but I think it is. Keep in mind the median income in the nation, amongst working people, is only 31k/year. And that's before taxes, rent, etc. Sure, if you have two working, healthy adults in a household, they can swing 1k, but it's still a huge expense to the average family.
I'd say it's for any single employee (with the young being ripped off if they pay that much).
But yes it generally doubles or more for spouse or family coverage.
