The revelation of that stark difference comes courtesy of the Dodd-Frank Wall Street Reform and Consumer Protection Act, which required companies to disclose the ratio between their median paid employee's compensation and their CEO for the first time this year.
In the tech world, where many CEOs take tiny salaries, and receive most of their pay-out through stock sales, the actual ratio isn't very revealing. For example, Alphabet CEO Larry Page only made a salary of $1 in 2017. But, he also owns 42.5 percent of Alphabet's Class B stock and is worth nearly $50 billion. So the ratio of his compensation to his employees' is meaningless.
