VC funds with dozens or hundreds of investments may like a landscape where one or two make a 10x or 100x valuation and the rest go bust chasing that goal, but I personally can't afford to gamble my family's future with my 2,000 hours per year on a 1% chance that my employer will rocket to the moon. Also, job-hunting is a pain, I'd prefer that my employer not go through massive layoffs or risk bankruptcy unnecessarily. Equity growth or profit-sharing bonuses are just that - bonuses, mostly ignored when comparing total comp unless the 'bonus' is extremely stable and reliable. I need to take home a reasonable salary in exchange for my labor.
Even if you're wary of startups you have a founder that seems set for a predictable direction instead of hypergrowth and you might have a better chance of it not going bust next year. Then again if you're in it for the shares and the big opportunity, then probably not.
