I believe you misunderstood my comment. I am not disagreeing with you. There are organizations that properly value people's time and make sure that overwork is both rare and rewarded. I'm lucky enough to work in one. But, even in those organizations, it doesn't just happen by itself. The management in your company is working hard to keep leadership in check and communicate your value. Because if they don't, organizational inertia will result in your team getting more and more work (or losing resources to do your existing work), no matter how great your company is.

It's not magic, it's good leadership and management.
