Could technology have improved the lives of the Luo Tribe in the book Yes We Can?

Yes technology can improve the lives of the Luo Tribe in the book Yes We Can by building better homes. Currently homes in the Luo tribe use mud and grass for home structures. Homes could use stronger materials such as aluminum. 

Aluminum is a silver white light metallic chemical element that is easily worked, conducts electricity well, resists weathering and is the most plentiful metal in the earth's
crust.
