Because it may well have happened a long time ago before you and I were born! From my reading of history it began in the early decades of the 20th century and was solidified by the development of the “education industrial complex” in the 1960s. Now in the early 21st century we see this corporate public education system finally showing signs of collapsing due to the weight of its bureaucracy, corruption, regimentation, and entrenched interests. And as a result we see all the business foundations desperately trying to revive and sustain it, and the many billion dollar business market it represents.
