No, sorry, you don't get to say your claims are well documented without providing evidence and then demand I provide evidence in the same sentence.
Also, realize that universal health insurance doesn't equate to no private for-profit insurance companies or that there is a single-payer. For example Germany has a multi-payer model with both private nonprofit and public for-profit insurance options. IIRC Japan is privately owned nonprofit with single payer. And Italy is single payer with a sort of hybrid public/private delivery structure. Shit is complicated.
