In response to the aforementioned question, i get the impression these "tiger moms" are "living" via their gifted daughters/sons. That is, their success as a gifted individual serves as a conduit to feelings of satisfaction and fulfillment--especially if the parent's lifestyle is less than satisfying. I would not worry about these situations; these overly-competitive mothers and fathers are simply comparing when they should instead focus on the needs of the children. These sound more like insecurities needing resolution within the parents.
