People who are paying insurance premiums and taxes currently put money in two areas we&#x27;ll call &#x27;insurance&#x27; and &#x27;tax&#x27; for convenience sake (and because it accurately reflects reality).  The money in the &#x27;insurance&#x27; area goes toward paying private medical costs.  If those private medical costs disappear and are shifted to public costs under a single payer plan, they don&#x27;t go away, merely move under that other column.  From then on, no money need be put into the &#x27;insurance&#x27; area.  Yay!  But now, the &#x27;tax&#x27; area has to pay out more since it took on those costs so much of the money that would have been put in the &#x27;insurance&#x27; area must be put over in the &#x27;tax&#x27; area to cover the medical costs that have not disappeared but been recatagorized in terms of what pool it is paid out of.  Even if those private medical costs are halved somehow,  saving the payee money in the process, the &#x27;tax&#x27; area would still need to be bolstered to handle the additional burden.  Thus, higher taxes even though overall money is saved.
