Yup - that poor elementary school teacher would have to work for 40 years to get ONE kid at the 1:1000 level, and another 40 years before he/she saw the second one! Of course that is just at the school with a mythical normal distribution in it's school classroom. In the U.S. we segrate ourselves by economic circumstances, which over broad numbers has an effect on IQ/school district.
