"I'd rather have a work and life balance that I can enjoy."
Which has nothing to do really with working overtime and everything to do about how you approach work and life. I think one could boil down the philosophy into 'if you're working too much and your balance is out of whack, then quit.' And it is quite reasonable. In the Bay Area families can be especially hard hit by people who over commit.
That being said, in spite of the Author's disdain for economics, the interrelationship between who is available to work, pay, and whether or not they are willing to stay, does 'fix' the problem magically.
