Einstein and Beethoven were both total slobs, too. Dunno about what you're describing. IQ probably doesn't have a whole lot to do with it, though.
yeah, they were both very famous, why's that? Why are most of those slums welfare cities? apples and oranges. And oh, maybe IQ.
Doesn't take many smarts to know to pick up trash and keep your children healthy. Oh, high IQs can figure out you don't make babies you can't support.
Intelligence plays a role as well as education but genetics plays the greatest role and along with morals, religion and culture a people can be defined and or judged.
Yet, despite all the evidence of the truth of what I have posted above....our government comes in and denies the truth, denies reality in fact by presenting and enforcing polices that go against all common sense and the experience and knowledge of our forefathers who were much wiser than we.
So today as we speak we see the results of decades of liberal social engineering and experiments being foisted in particular on our children that have resulted in social chaos and violence that is only increasing along with our debt .....much of which was incurred by pouring huge amounts of money into failed social programs designed with good intentions but simply never worked and never will work....you cannot go against nature...you must deal with reality if you want to improve society....living in their ivory towers of idealism the elites with all their power have messed up the greatest nation on earth.
