Then I suppose you'll agree with my statement that IQ is only one facet of intelligence. Also, there are certain biases in IQ tests, although they are somewhat overstated. It would be hard to assume that there is a white bias when East Asians are the highest scorers on IQ tests, typically.
And yes, being streetwise is quite important in many contexts. In an apocalypse, however, naturalistic intelligence is the most important, which is most prominent among many rural whites -- the same whites that many of you have been making fun of.
Many rural whites also have practical skills that are needed in rough times and good times alike (like mechanic skills, electrical skills, plumbing skills, etc.).
So, education comes in many forms -- not just the 4 year variety. A person who goes through community college to become an electrician or plumber won't have massive student loans to pay off and will have a good paying job right out of college. Many of these people end up running their own businesses later on.
