It is an accident of history that old stories are recalled in black and white.  Familiar, faded images.  Always the same.  They never tell it all.  During the Great Depression of the 1930’s, farmers from half a continent funneled into California looking for work. Leo Hart helped their children find a way out of poverty.  He taught arithmetic in an air plane.  Children with the highest marks got to taxi it around.  Those kids ended up owning mining companies and supermarkets.  They became college professors, engineers and judges.  Their teacher emphasized what they could become, not what they were.
