Who profits most from America’s baffling health-care system?

By The Economist

The country spends about $4.3trn a year on keeping citizens in good nick. That is equivalent to 17% of gdp, twice as much as the average in other rich economies. And yet American adults live shorter lives and American infants die more often than in similarly affluent places. Pharmaceutical firms and hospitals attract much of the public ire for the inflated costs. Much less attention is paid to a small number of middlemen who extract far bigger rents from the system’s complexity.
