There is a bubble here. Running ones own business is, on the overall, better than being employed especially given the current world. However, that doesn't automatically equal to startups. There are people who are running their own brick and mortar businesses. They're not billionaires or even millionaires but they've crossed the point where lack of a reliable source of wealth is a source of misery for them. Surely, that's a great thing.
Healthcare is one place that gives me pause when considering going back into business for myself and my family while living in the US.
I guess it depends greatly on where one lives etc. This is a concern I've heard from all my friends in the States.
This is definitely a concern that needs to be addressed if we want to see more small businesses again. It's a big risk not having health insurance.
