Most companies aren't startups, in the HN/YC sense of the word. I was addressing the majority scenario.
First employees in startups are playing a different game; a combination of risk and novelty. The employees are gambling on stock options and a payout (not a particularly rational gamble, of course); but they're also working on new technology, greenfield development, in an exciting environment, often with younger people who are less, shall we say, "conservative" in their career trajectory. All of this is utility to such first employees; and it compensates for salary, depending on their utility function.
As a company ages, the profile changes. Depending on how the employees have changed along with it, they may seek a different mix.
they may also get no stock or options. when they are young, recently educated, as you say they will jump on for the combination of novelty and a chance to grow and extend themselves.
when it comes time to pay them fairly, either after they have acquired the experience or simply you raise enough money to do so, fair becomes determined by what they get elsewhere.
