Also why doesn't balance mean "now you've earned an extra hour or two mid-day for yoga, 0 judgement"? I call it the "retail-worker mentality" when I point it out in friends. It isn't meant to deride retail workers, but to draw attention to the inhumane people and conditions they live under. The conditions aren't justified at low pay nor high pay, and people need an impolite analogy to have this simple but life-changing epiphany. Just look at the deathbed surveys of happiness and regrets.

If I do good work for a rich, high-margin company, I'm going to act like it (towards the employer) and reap the rewards. Because if I don't, someone is, and they're up the chain, so let's pull those rewards back down a bit and reclaim our humanity, ok? This isn't entitlement, this is taking the rewards I've had a hand in building rather than leaving them on the table and saying "thank you for letting me leave these extra 20% of rewards to you".

Separate from this, I might vehemently advocate politically for reversing the upwards redistribution of wealth to the tech elites (me), and that's not hypocritical. Hoping for Richard Stallman-level principaledness among the professional working public isn't the answer to political and social problems such as this, so let's not armchair and claim that working half your Saturdays moves the needle towards wealth fairness better than saying no and going home and taking the paycheck. Inconsistencies can coexist without resolution, and most of life is exactly that. If you can't live with it, then the answer is to quit, not routinely work Saturdays.

The company's budget has room for more staff if it's truly needed (it's not); my life budget of personal hours does not have room for more work, nor should it if my employer is among the wealthiest in human history.

Germany's auto-workers union negotiated a 28-hour workweek. Like them, we shouldn't be ashamed to rebalance our lives towards leisure, personal hobbies, personal relationships, etc, now that technology is so productive. In general, why is it wrong to favor broader participation in the fruits of human effort? I'll do my part by going home and taking the paycheck. Now I have more time and financial security to spread my politics if I want.

Elon Musk is right that companies and communities are fully and precisely the human-machine cyborgs of fiction, just at a different scale. Can that apparatus rebalance towards leisure etc? I think yes, so I'm taking my paycheck and going home early. It's not entitlement, it's living my valid and reasonable politics.

If this post seems off topic, then maybe you haven't thought all the way through what "sure, I can give you more hours of my life" means when you offer it to an employer. We might disagree on some or many points, but all of this post is directly relevant to that negotiation of hours.
