The gap isn't just that between the rich and the poor. It's also between the well educated and the ill educated. Kids are coming out of school, unable to read or write to an acceptable standard, and most of them are lost without a calculator to sort out even the simplest sums.
There should be a minimum standard which kids MUST attain, before they leave school. I remember kids whom I went to school with, being made to repeat a year, because they hadn't reached the standard required to go up into the next class/year. I suppose in these days when kids leave school with a certificate, whatever their exam marks, they wouldn't dream of doing such a thing.
Judging by some of the written applications for jobs I have received, I would suggest that a large proportion of the unemployed in this situation, are unemployable.
