You are still paying for the Ferrari treatment by hiring older workers in terms of better working conditions: those workers are wiser to the usual corporate bullshit, are unlikely to be doing unpaid overtime because they "believe" in the "mission", require better work/life balance and are financially-secure enough to afford to tell you off if you cross the line.
Not to say it's a bad thing, it's great if you managed to get your company to deliver a working environment that attracts and retains older workers, just pointing out from experience with techbros that the reason older/more experienced workers are avoided (or just don't apply in the first place) is precisely for this reason - techbros explicitly don't want someone who can afford to defend their boundaries, they'd rather take someone who's too naive or financially-insecure to say no.
