Yeah, you need to change people, but those people need to be alive before they can be reformed. That is to say, in general, the education that you want to push on those in poverty really only matters and can only take effect when those in poverty have at least a modicum of stability and wealth - enough for food, basic medical care, and water at the very least. Laptops are entirely useless without that base. It's an infrastructure that underlies that of internet connectivity.
