This is only true for those rare positions (senior/upper management) that offer such equity grants, or if you lucked into one of those one-in-a-million rocketship growth companies. I've been in the tech industry as an engineer and lower/middle manager for 15+ years and equity has never ended up making up even a tiny fraction of my compensation. Often it ends up being worthless (underwater options). I suspect my situation is the more common one.
