First of all, I found your statement very degrading Sporeans.
And it been few decades now, did not see gene improvement as you mentioned. 
What more observable is many left with their husbands or some with wife overseas. 

The loyalty is low compare to the past. And my honest view, our military edge is no longer as it was
No one is treating Sg with respect compare to twenty years ago.

The improvement is due to import of FTs-new citizens.  They raised the national IQ.

If we had succeeded in getting locals to make babies, I doublet we would be as intelligent as a nation as we are now.
