plan to change the perspective and talk about some of the more famous oligopolistic companies in the world.<\/p>\n\n\n\n<p>Please note that there is one difference between an oligopoly and a monopoly: a monopoly is basically certain to make money because there is only one company that controls the entire market, but an oligopoly is not necessarily certain to make money because there are multiple companies sharing the market. The best example is the US airline industry. Although it is controlled by a few operators, each of them has suffered heavy losses for a long time.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Strategic_Consulting\"><\/span>Strategic Consulting<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>McKinsey and Boston Consulting Group are two groups that can be said to have monopolized most of the global strategic consulting market, but both companies are private companies.<\/p>\n\n\n\n<p>Accenture also has a small number of strategic consultants, but the business volume is very small.
