In 2021, Alphabet (Google’s parent), Amazon, Apple, Meta (Facebook’s new alias), and Microsoft were among the world’s largest companies in terms of revenue and profit. These five companies alone increased their market capitalization by an amount greater than Italy’s GDP ($2.5 trillion vs. $2.1 trillion). Big Tech now accounts for nearly a quarter of the S&P 500’s index and a quarter of research and development spending by US publicly listed non-financial firms. Amazon is the world’s fifth-largest employer, and it is still growing.
