Trick question?
I mean... it's a choice of....
Businesses =Private Insurance> Healthcare
and
Businesses =Taxation=> Government= Public/Private Insurance> Healthcare
First of all, it's not necessarily true that businesses have to be taxed higher. Taxing individuals who can afford to pay is a much better route. Businesses can leave America but individuals cannot (will not, I should say lest I sound like Ron Paul). Lower the burden on businesses.
Also the question is who can keep Healthcare inflation in check the best. I don't think the current system has been doing such a good job of that, wouldn't you say?
