In a pretty shitty one. That is the ultimate goal of modern cut-throat capitalism: get utter market domination, destroy all competition and once that is done, raise the prices as far as possible without attracting too much protest from the few regulatory institutions that remain.
True, but the only way they can achieve that is by using the government to outlaw competition and/or regulate them out of existence.
Their attempts to do it result in prosperity, high standards of living, longevity, etc.
(it has nothing to do with being "modern")
