All projections of rising healthcare costs assume that advances inmedical science will add to the cost. This is a reasonableassumption, since it has been uniformly true in the past.Antibiotics are a great advance, but bacteria develop resistanceand newer and more expensive antibiotics must be developed. Peoplewho would have died at home in the pre-antibiotic era now survive,but after the greater cost of antibiotics and, possibly,hospitalization. The same is true for advances in cardiac stents,cancer treatment, imaging with CT scanners and MRIs, etc. Thetechnology can be life-saving but is typically expensive.
