At some point you have to acknowledge that a substantial portion of your population is in the bottom 10% of the IQ distribution. Holding them to behavioral requirements isn't going to really change their behavior.

Say what? How can 10% of the distribution be a "substantial portion"? Ten percent is ... ten percent. For a normal statistical distribution, 10% of the IQ distribution is normally 10% of the population as a whole. To see why, ask yourself what percentage of the population is at or below the 50% IQ level. Then, having pictured that, ask yourself how 10% of the population could represent "a substantial portion" without contradicting what's just been demonstrated.
Your remark reminds me of the special conditions in fictional Lake Wobegon, where all the children are above average.
