Minister Mentor Lee Kwan Yew on "Assortative Mating"

According to Wikipedia,

Assortative mating (also called assortative pairing) takes place when sexually reproducing organisms tend to mate with individuals that are like themselves in some respect (positive assortative mating) or dissimilar (negative assortative mating). In evolution, these two types of assortative mating have the effect, respectively, of reducing and increasing the range of variation, or trait variance, when the assorting is cued on heritable traits. Positive assortative mating, therefore, results in disruptive natural selection, and negative assortative mating results in stabilizing natural selection.

Minister Mentor Lee Kwan Yew recently touched on his definition on "Assortative Mating" in Singapore Human Capital Summit 2008.

MM Lee comments:

“That is the way the world is. I have explained this. I think I lost votes after I explained the awful truth. Nobody believed it, but slowly it dawned on them – especially the graduates – that yes, you marry a non-graduate, then you worry about whether or not your son or daughter is going to make it to the university!”

I personally do not agree with MM Lee's above comment.
