I feel like the work ethic I see throughout the industry is extremely toxic to society, and leads to some of this. In China for example there's a so-called "996" work schedule (9am-9pm, 6 days a week) which is basically expected of everyone in tech, unfortunately, and it seems Silicon Valley is heading that direction as well with all the off-hour meetings, weekend work, and on-call requirements. Many SV companies also demand 72 hours or more of work per week, in my adecnotal observations.
What I'm often observing is:
(a) such toxic work ethic is largely set by male founders who don't care about other important things than work e.g. family plans
(b) others in the industry are forced to compete with those ridiculous standards, including females, those with disabilities, those already with family, those taking care of a family member, etc.
(c) this results in those groups being consequently disrespected by investors because they can't match up to the workaholic male founders who don't care about anything but work. I've heard several investors talk negatively about females behind their back because "they might want to have kids".
(d) this results in more workaholic male CEOs rising to the top
(e) the cycle repeats
Are my observations and inferences correct, or am I off? Open question here.
