>Any system that knowing allows that many children to NOT receive a full education is a bad one.
Not all children are capable of achieving a full education. IQ matters.
IQ is one thing - being denied an education because an employer is unwilling to sponsor you is quite another. But that is the system here.
You CAN NOT go to school and get a diploma (i.e. 10 - 12th Grade) unless you
1. had very good grades in “BEZ” level (and generally are going to go to college), or
2. you find an employer willing to sponsor you for 3 to 4 years. You will work full time, for very little pay and attend school once or twice a week.
