The tech has changed much since I posted this! The POS system would defiantly be the way to go in this situation.
as for the doctor vs babysitting, In my humble opinion the training that doctors go through is way to costly and for that justifies a higher pay. However the high cost that doctors demand draw more people to do that job for the money rather then just being a good human. I would much rather someone looking after me enjoy the position rather then simply earning a paycheck.  Naturally in our current culture and monetary paradigm much of this is just a dream.
A system such as that would require a Universal Income system to off set many of the greed components of society. Of course UI is a touchy subject.
Thank you for your input.
