That makes it easier to quantify. If I need to work a decent job at a decent company to have good healthcare, then a large number of people don't have good healthcare.
This is not acceptable. Healthcare should be a basic right, and a lot of European countries treat it as such (e.g. in Germany, everyone is insured, no matter their employment status, and its mandatory and equal for everyone regardless of their job).
People also can't be fired for being sick.
