I don’t see why healthcare is all an employer’s responsibility.

It evolved that way in the US because the government imposed wage controls and the only way employers could offer their employees more was by increasing benefits - like healthcare.
I don't know of anyone who thinks it's the best way to do it today but we're living with a system that grew up over many decades.
The main thing keeping the system in place is that employers can deduct the money they spend on employee healthcare but individuals buying their own insurance can not.
