Because FDR put on wage and price controls during WWII. White collar workers were leaving for other jobs. Then companies started paying for healthcare to get around it. It became an untaxed, and unseen benefit. Then it became the norm with unions and other jobs. People became unattached to the cost. Now some people think it’s a right. Socialist solutions create bigger problems for capitalism. Solution need to be capitalist solutions. Like eliminating the restrictions on the number of doctors. Artificially put on by Doctors associations.
