Great for Dangote, and Nigerians should be proud of him. Given his influence in Nigeria, he can do more, especially in pushing the government to build better infrastructure. It is a shame that a country the size of Nigeria lacks a rail network, for instance, so Dangote has to truck his goods on Nigeria's terrible roads. And, sadly, Nigeria's most dire needs may still be water and electricity -- quite unfortunate in 2012. With clean water, we solve a lot of our health problems. And, with electricity, we cut down on pollution from generators; businesses run more smoothly, and the security situation also improves significantly. People like Dangote can push elected officials to do the right thing. Nigeria needs leaders with vision and know-how.
