Maybe you need to challenge where your values come from and who they benefit. There is nothing so urgent that people need to work 12 hours a day. There is (for most people) nothing that you will value from your time of working hard for a tech company in the future, except perhaps money. If you turn your argument around, people who want a good work-life balance hate people like you because you are willing to die for your corporate master and contribute to the dog-eat-dog mentality that wrecks people. There is something reasonable between 2 hours a day and 12.
