I wouldn't have nearly as many complaints about this mindset change if ones life (e.g. insurance) weren't still so deeply tied to who your current employer is.
I don't know what the best solution for the current healthcare clusterfuck in the US is, but I think disassociating health insurance from employer/employment is a great first step.
That should be the goal and once we have that, it will not matter if you are self employed or own a business. We keep doing half measures and pretend to be surprised when it doesn't work.
