I'm not saying that a student who only shows interest in building an engine (for example) shouldn't also be taught to read as a matter of course, but not caring about the tyrannical regimes in Africa is not necessarily a sign of laziness.
Is it tryannical regimes or humanity? At work, people dont seem to realize that there is a huge world out there and because of improved transportation, communication etc, what is happening in Darfur, Iran, Iraq, India, Sri Lanka, the Balkans is not that far removed from us in reality.
