I already signed up and paid for my ACA policy, and love what it does for me.
But I recognize the challenge for people with families. They've been subsidized by corporations at the expense of childless couples and single people for years.
I think a better fix would be for people like me to pay $50 more per month so policies for people with kids would be less. We want to encourage people to have children.
I wouldn't count on that subsidy from corporations continuing-- my last corporations had cut benefits every year of the last seven years AND rates for children and spouses had increased for at least the last three years.
In my case; the ACA has allowed me to retire and start several small businesses instead of working another 16 years (despite not needing the money) because of my preexisting conditions. Since I don't think it's likely I would have been able to find employment with insurance all the way- an uncovered period was probably in my future.
