> I _strongly_ disagree with a fully cynical response of working only to contract, leveraging job offers for raises, etc

Would you consider employers to be "fully cynical" about their affairs and interactions with employees? I do. Being a happy little cog is it's own reward, but ine has to be clear-eyed about it.

> If people know you are a standout contributor then you will be hired quickly into desirable roles.

You are presenting a false dichotomy - one can be an outstanding contributor while working 40 hours per week.
