It might not be on the official syllabus but education is more
than just what is formally taught. As you pointed out,
indoctrination starts with the family and kids bring these values
to school. When almost everyone think like this, then it is very
likely that a child will be so influenced.
You say that this phenomenon is common in the west, I can tell you
that is not true. To be more explicit, the level of indoctrination
is not as strong as in Singapore. In most western countries, people
recognise that life is not solely about your paycheck.
