Kenya: Africa's rising middle class. For the past years, Kenya's economy has enjoyed a sound growth rate. Although sixty percent of the country's population still lives in poverty, the middle class is growing. Richard Kimani is an entrepreneur who got his start as a distributor of mineral water. Meanwhile, he has also become a successful juice producer who has nearly 360 Kenyan farmers under contract. Much of their mango harvest used to rot and go to waste - but now Kimani turns their fruit into juicy profits.
