Zimbabwe indeed has got one the most affordable education system ,no matter where you live there is a school easily accessible.Also education is the biggest employer .However its really hard a tertiary level to get the most out of your education because of the economic situation.
I agree with author,you can still accomplish a lot of things with limited access.I just launched a website http://www.mixdem.com from internet cafe in Zimbabwe , Africa.
IQ is very biased depending on the environment you grew up.if u grew up in zimbabwe or a country with high literacy levels the iq tests will be just too easy.
