Even within sectors, we see the pattern. For example, the two fields of medicine which have seen the least cost growth are cosmetic [1] and laser eye surgery. Not only have costs risen the least, but the quality of some procedures in these fields has improved tremendously over the last two decades. Both are electives, so there are fewer mandates requiring that they be covered by insurance and fewer redistributive programs to subsidise them.
The source of the complex system dysfunction is the political and social system, which enables special interests to mislead the public in order to implement policies that benefit themselves but have a negative-sum impact on the economy as a whole. One of the 'big lies' that these special interests have succeeded in convincing the public of is that the free market is a misguided ideology that is promulgated by the rich in order to exploit the poor, when in reality it is a basic rule-set necessary for economic development in complex systems (due to properties like the rule-set enabling effective large-scale coordination of economic resources through price signalling, aligning private incentives with the public interest through laws granting and protecting the right to property produced through one's own efforts, or acquired through trade (and inversely, prohibiting acquisition of property through theft, armed robbery and other non-voluntary and predatory means), etc).
