We are presented choices; Coke vs. Pepsi, KitKat vs. Snickers, etc. Tracing back 99% of products we are offered as choices leads back to 10 main corporations. While these represent the retail market, the same is true for most components of society, politics, defense, computing, healthcare. Also interesting is how although even the 10 corporations are 'different' entities, they all work together in a big happy corporate family. Coca Cola doesn't own Monster drinks but does their distribution. Executives of companies may sit on the other's board. Sometimes a competitor will buy a division of the other, such as the recent sale of Pringeles to Kellogg's.
