They do not have the requisite number of MRIs CTs etc.
They do not have adequate ambulance services (I am
talking about the equipment, not the Paramedics). They
still have hospitals with open wards (nearly all of the hospitals
in the US are private rooms only). It is a matter of adequate
resources, research, surgical techniques etc. It is not an
accident the twins co-joined at the head/brain come
to the US from all over the world to be separated (at
no cost to the parents).

It would be interesting to see some actual figures of the efficiency of
medical systems around the world.
