Amancio Ortega to be the world's #1 billionaire by 2017

Amancio Ortega, the founder of the fast-fashion empire Inditex, could have never predicted the success of his Spanish fashion empire when he opened the first Zara store in 1975. Fast-forward 40 years later and Ortega is poised to surpassed Microsoft co-founder, billionaire Bill Gates in the Forbes Fortune 500 as the richest man in the world within the next two years - quite an achievement for a man who first began his career in the fashion industry selling quilted bathrobes.
