Not on a theoretical level, but how would you practically have to pay costs, access specialist doctors?
Yes it is. And besides the premium and other costs, we also pay taxes for care for the sickest and the oldest. These private insurers are cherry-picking the group they insure and still charging the outrageous fees, raking in profit and outsourcing the more expensive groups to the rest of us to pay for. So I get about half of my paycheck as netpay after medical, tax, HSA and 401k; same as someone in a socialized nation, but without the assurance of healthcare or a pension.
