TBunny-
Okay, what's a 'bingo'? A 'ding'?
My husband and I also are both highly educated...and we've had people say...'oh, you are so smart, you'd have such bright kids...we need more good people like you as parents.' I take comments like that as a sort of compliment...but when did this become some sort of contest of genes between the smart and the stupid? Is that a really good reason for popping out a kid?
As far as the IQ precipitously dropping in our society...I think it is based on a few reasons...which some may find offensive...so buckle your seatbelts....genetics is part of my graduate studies so....I think it is partially because our medical science has developed to a point that we can keep babies alive that 'nature' would have eliminated from the gene pool by selection.
Additionally, as I've said before, it doesn't take much to get pregnant...you don't have to be a rocket scientist....just insert Tab A into Slot B.
Then there is the macroscopic issue of us as the human species being quite disconnected from nature in modern times....especially in Western industrialized countries. We are more shielded from natural catastrophic events like floods/disease/famine/fire that would naturally check the population and promote 'survival of the fittest'.
Lastly, statistics show that the higher the education and income level of the parents, the fewer children they have....ipso facto...we CF must all be rich geniuses! Ha ha! Might not be a linear correlation

. It, therefore, follows that those with lower intelligence and income are the ones doing most of the breeding...which would cause the downward trend in average IQ. Sorry, truth hurts.
Anyway, Western Europe is actually going to have a big problem with their social welfare programs because the birth rate has dropped so low there won't be enough new 'workers' to support the elderly. The demographic pyramid has flipped. The majority of the increased birth rate in the U.S. can be attributed to immigrants, actually, not native-born citizens.
And yes, you are right, we are the only species to which natural selection does not readily apply anymore....unfortunately.

Okay time for me to go to work.
