The asian kids that do come out hardworking and studious from our tiger parents are not all rainbows and sprinkles either, as many are stunted in emotional development and social communication due to the extreme discipline and pressure we had to deal with growing up.
Lastly, and most ironically, asian immigrant parents always push their kids to be the best, and being "good enough" is never enough. The pressure to achieve, the detached politeness of the traditional asian culture -- there are plenty of cracks that a misguided teenager could fall into.
"Good enough" can be applied to job, money, work, and any other tangible thing. But humans and emotions make the world go 'round, and when you have the future of an innocent, malleable human being in your hands, there is no such thing as "good enough" parenting. That is the entire dilemma being discussed here for women - compromising to be "good enough" at work so that they can be "good to the best of their ability" for their children. Not the other way around.
