Hmm.. well if they waive the 70 bucks from the patient, then it
must come from the taxpayer, in the form of raised taxes. However
if, as you suggested, we get the 70 bucks from the salaries of the
'upper hierarchy', then i certainly dun mind... 
Anyway for the genuine needy who have trouble paying their hospital
bills, they'll be referred to the hospital's Medical Social Worker
(MSW), who'll look into the matter and coordinate with the hospital
to help the patient. Our system is such that basic medical care is
always available for all Singaporeans... it's only that if you want
better service/better drugs etc, then you must be prepared to pay
more.
