i'm licking my chops on this one, but i'll try to be restrained:
- mass education has gone far off-course. teaching the fundamentals of reading, writing, math, and some civics content (the needs of most people in a democracy) have been replaced by weak "college prep" courses and even weak university degrees. all of this seems to be driven by the "business" of education.

most people would be much better served with fundamental education to about 8th grade or so, some techincal/internship type of program after than, and then (this is key) the right/ability to re-enter the formal education system at a later date should they want to (e.g., to pursue properly rigorous high school, university, and graduate degrees) with some kind of conditional financial support. this would wreak havoc on the education "ecology", so it will never happen in the US or UK, but it's still a dream.
- "getting smarter" is a very tricky concept when using IQ as a measure. first, IQ was designed to be a relative measure, not a static one. 100 is supposed to be the average. even if you standardize it to measures at one point in time, there are still two potential issues. first, as excession suggested, you can improve "brain power" via an improved environment. i would suggest that this includes better nutrition, better overall health, and even being raised in more intellectually-stimulating environments. the second relates to error in IQ tests, and i'm going to give that it's own bullet point.
- IQ tests have a great deal of type II error. what this means is that it is very difficult to score substantially higher than your theoretical full potential, but it's VERY easy to score quite a bit lower. bad night's sleep? no breakfast? argument with parents/siblings/gf? illness? stress? simple ambivalence towards the test (common in young children)? all of these things can lower one's IQ test score SUBSTANTIALLY. one might say that most of these factors have been relevant in the past as well as in the present, but i would suggest that home conditions and testing conditions have improved in modern developed societies.
- cultural bias does have a fairly substantial influence on results, but you can get around this by designing tests for relatively homogenous groups. i realize that this is not really possible given the extent of modern-day diversity, but it is theoretically possible. the non-politically correct stance these days is that the test is aimed at being biased towards the majority (usually middle class) and that minorities will need to learn to adapt to this way of thinking if they want to succeed anyway. this could start an interesting discussion of oppression, etc. that i have no interest in getting into. i'm merely reporting what i see to be the
de facto stance of those in power.
this was supposed to be short....
