NYT article: A Different Kind of Homework for Singapore Students: Get a Date
In a successful, benevolent, conformist, paternalistic state, risk avoidance is an optimal strategy for personal success. However, those who succeed may come to apply this strategy much too widely. Having kids is a big investment entailing lots of risk, no matter who you are. It is a risk which managed society in Singapore has not yet formulated an effective insurance policy for.
The decision to enter a marriage and have children is a personal one, the expense and success of which are determined in large part by how your personal conditions for happiness are structured. If you were truly conformist, there would be no problem with settling, but I would guess that that is hard to jibe with the self-image of the young single professional. People underestimate the difficulty of being happy AND unique.
