I believe this is incorrect even from the simple economic perspective.

Many companies (BigTech for example) are extremely net-positive financially. This means that the value they gain per employee is much higher than what they pay them.

Taking this further - the customers in many cases (and certainly in ideal cases) are getting more value than the price they are paying (hence they agree to pay), so in a sense you could argue that the value is actually even larger. This of course scales several times when working on some infrastructure (though the effect is very not obvious).
