Does universal health care benefit the people, as much as it does business?

Many people in the US receive health care from an employer, or purposely work less to qualify for free health care, or stay in jobs they aren’t suited to to stay insured; some people do not start businesses, or hire the fewest staff possible because of the cost of providing health care. These all contribute to economic inefficiency and generally hurt productivity.

Would government funded universal health care actually be a bigger boon to business than to the people?
