Employer-provided health insurance is not some gift from benevolent feudal lords and ladies but
part of the worker's overall salary/wages plus benefits package. When someone accepts an employment offer, that "someone" regards the whole compensation package as compensation.
I would much prefer that health insurance be detached from employment altogether, but if that cannot be achieved we should not let ourselves be driven into a situation where
someone else is expected to subsidize those salaries or wages because of religious scruples by the said feudal lords and ladies.
