Revenue per hour per employee of the big tech companies

The number of employees looks off, I wonder if the author used 2021 end-of-year numbers? And maybe 2021 revenue numbers as well? This is current employee count I see on Google Finance for these companies (number in brackets is from the Twitter post):

Amazon: 1,608,000 currently (1,298,000 in original post) 24% increase

Apple: 154,000 (147,000), 5% ⬆

Alphabet: 163,906 (135,300), 21% ⬆

Microsoft: 181,000 (163,000), 11% ⬆

Meta: 77,805 (58,600), 33% ⬆

Netflix: 11,300 (11,300), this doesn't appear to have changed?

Amazon's a real outlier there, presumably because it doesn't outsource services that make heavy use of low-skilled/low-paid workers. But is that necessarily a bad thing? To what extent do Apple etc. rely on other companies doing "dirty work" for them to ensure only high skilled employees are on their payroll?

Perhaps we should judge companies by profit per employee per hour and aim to increase that

Wouldn’t that be better than just valuation ?

For reference that’s 85k on the low end (Amazon) and 663k per year on the high end (Netflix).

It’s an interesting thought experiment to wonder what it be like if the workers at Netflix actually took home that kind of money.
