FTFY.
The original quote was about their ability to poach employees.
What does it mean to poach an employee? It means to convince the employee to make the major life decision to work for them instead.
Why do people choose to make such a major life decision? Usually it's because they think it will make their life better.
Why do they think it will make their life better? Because the FAANG offers >= 70,000usd to switch jobs, pays for them to relocate and sell their existing home, offers fully paid health insurance for their entire family, offers hundreds of thousands in stock options, and an unbeatable salary.
This is how they convince engineers to work on the world's most effective attention machines. By making their life better in all these ways and more.
If you fail to understand that, if you fail to engage in any kind deep or abstract thought that isn't summarized by a four letter meme, then you're doing exactly what this article warns you not to do - you're underestimating FAANGs.
Edit: I should add, it's probably mostly about the money. I mean, nice office, all the perks, all enabled by money. And for most people a very material raise in pay makes a difference
> Never underestimate how much better a person's life can be by working for a FAANG instead of working for you
Edit: For those who are downvoting, I'm simply saying this is what's implied by the quote. I'm not making a statement about FAANGs.
