I did buy obamacare for a year or so but now my wife works and we use her health insurance. I will be in deep shit if I have to buy out of own pocket (family of 4). So yes, that helps a lot as well.
Yes. This is common (in the US) for solo business people with families. When I talk to self-employed people, few want to discuss health insurance. The topic seems to be taboo. Maybe some are going without insurance? Obamacare does not address the issues of a solo business owner. As far as friends who run solo businesses, those who would discuss the topic all said that they had their wives get random corporate jobs (e.g., at a retail bank location) to provide health insurance.
Health insurance is a must here and can easily add up to 500 Euro or sth. like that per month when you got a wife (not working full time) and children.
So getting ramen profitable is possibly much harder.
