Since the 1960s IQ in the US has declined to 94 from low IQ over breeding and low IQ majority immigrants allowed.
It is interesting because I had read where it took an IQ of 96 to make journeyman in 10 years in most trades. 
Schools have dumbed down and reduced requirements and courses offered.
In housing sloppiness has become accepted. 
The PHD Professor who first brought this up was canned for so called "racism".
The book that had the extensive data to prove it was ostracized. 
From Science News; "Previous studies comparing twins and family members have suggested that not-yet-identified genetic factors{actually IQ tied most closely to race} can explain 40 percent of people’s educational attainment; factors such as social groups{again racial tendency}, economic status{again usually tied to IQ} and access to education would explain the other 60 percent{along with bad or incomplete parenting}. That percentage attributed to genetics is similar to the heritability of physical and medical characteristics such as weight and risk of heart disease.That makes a hunt for the genetic factors underlying educational attainment an attractive prospect."{when the truth is already known?} Yes, many of the lowest IQ are also the most obese, too. Most of those on food stamps are more obese than those not on food stamps.
I think it has affected our Senate with them approving an amnesty without any enforcement or thinking of consequences at all.

Who will pay the 18.9 trillion? 
Especially when the interest on our debt right now is getting closer and closer to the GNP. Who will pay for the decline even further of our infrastructures? ](./images/smilies/eusa_wall.gif "Brick wall")
Since high school I have watched this country go downhill from once greatness to wondering how much longer before collapse.
