The cynic in me says they have bad working conditions since they're public funded: governments, to a large extent, don't want to increase or divert taxes to provide better working conditions since they'd rather give their friends in the private sector a slice of the immovable and highly lucrative pie.

A partly-privatised healthcare system only works when all agree to balance the intangible long-term benefits of universal healthcare with tangible private-sector financial-gain. I don't see this happening when the private sector is seen as the panacea of all social-ills and when universal healthcare isn't seen a means to increase productivity.
