Monopolization in big tech is far more economically significant. The Big 3 cell carriers make $250 billion in annual wireless revenues combined. Their profit margin is about 15%. Google alone makes $300 billion in revenue, and has a net profit margin of 25-30%. Meta’s revenue is $130 billion and its profit margins are even higher, over 30%.
The tech industry is extracting vastly more monopoly profits from consumers than any other industry.
