Perhaps the raw number of jobs isn't the best denominator then, since many of the jobs in tech likely pay more to acknowledge this fact. A better measure would be something like the total of wages payed, or total of wages payed for the bottom 4 quintiles of workers by salary (cut out C-class executive outliers). Equity of course makes that harder, but most of the companies on this list are big enough that they're probably paying more in salary at this point anyways. I'd be interested to see where that places tech companies vs. more traditional businesses.
i think that's an interesting idea. instead of "how many jobs did we create?" you could ask "how much socioeconomic mobility did we create?". or something along those lines
