If I can interject.  I have a high school chum who always stuggled through school and left after grade 12 to sell cars.  He was quite successfull up until the advent of the internet and a new breed of salesman.  So at the age of 48 or so he was washed up....no formal education apart from selling GM cars.   He made big money, had a nice house and small family.  Now has gambled what he had left on small cap gold stocks, leveraged his house an has no idea how the new economy works.
This is a brutal work world out there and unless you  are employed by the city, government, fire department or any other cushy plush guaranteed jobs, all bets are off.  

Darwinism is alive and well and will eat the meek alive..This is globalization and the smart, savy, educated, tech adept  individuals will reign supreme. 

We are seeing a division of society that perhap will improve society by the lower caste indiviuals not having children, hence improveing the gence pool of homo sapiens.

Just a saying.....
