Some experts estimated that national health spending in the united states grew at 1% in excess of the growth rates of gdp. assume that this trend would persist for the foreseeable future, and given the fact that the share of gdp on health spending stood at 18% in 2016, what would become the share in 2064, 45 years from now (and 48 years from 2016, the base year), when most of you would enter the traditional retirement age? we should assume that gdp would grow at 3% annually. do you have a problem with the number you arrive at?
