In today’s global economy, corporate power has become increasingly concentrated, with a handful of companies dominating entire industries. From Apple’s 70% share of the U.S. performance smartphone market to Luxottica’s control of 80% of the eyewear industry, monopolies and oligopolies are pervasive. This consolidation, often unnoticed or ignored, shapes everything from the sunglasses we buy to the hotels we book, as companies like Expedia and Booking Holdings dominate the travel industry. While these monopolies operate quietly, their influence is profound, raising concerns about competition, innovation, and economic fairness.
