Tu show me in the constitution where healthcare is a right. It is a privilege.
It is of course not spelled out directly, but you could make a case that the phrase"that they are endowed by their Creator with certain unalienable Rights, that among these
are Life, Liberty and the pursuit of Happiness." could be interpreted as a provision for healthcare.
Let's say it is not though... I'll go that route, no problem.
Does the country not inherently become stronger if more people are healthy to work? If more people are not on disability due to preventive care?
Is that not in the best interest of the nation as a whole? Including reducing the cost for healthcare and in turn, saving us all money? If single payer is cheaper than your current insurance, and it's just as good, why would we not want that?
