How could the possibility of a modern day caste system arise because of the under- education of 21st century youth?

Many traditional fundamental guidelines and requirements for education have been vacated over the years. Nowadays, children are not required to think. They are encouraged to let the computer do the work. They are not required to learn cursive writing, the foundation for your signature, to validate documents. During the years after plantation slavery of Negros, being able to sign the given name was like gold to those who had been forbidden to learn to read or write. And speaking of slavery, as it relates to history, not only it, but other important aspects of our government have been deemed unnecessary education. In light of these 21st century changes, that seem to me, that are moving the country back to the dark ages, where is the leadership coming from? I'll tell you where; the leadership will be those who legislated the ignorance upon the new generations. Come forth a nation of "haves" and "have nots". Hence, the rise of the New World Caste System. Republicans and Democrats will no longer matter.
