CONTRARY TO CONVENTIONAL WISDOM, AFRICA HAS PROVIDED SEYDEL INTERNATIONAL INC. WITH TREMENDOUS OPPORTUNITIES, SAID RAIMUNDO MEIJA, PRESIDENT OF THE ATLANTA-BASED MANUFACTURER OF  SPECIALTY CHEMICALS FOR THE TEXTILE INDUSTRY. OUR PROFITABILITY IS HIGHER IN AFRICA THAN IT IS ANYWHERE ELSE IN THE WORLD, HE SAID, ADDING THAT THE MORE DIFFICULT THE MARKETPLACE, THE LESS COMPETITION HIS COMPANY IS APT TO FIND, AND THEREFORE THE MORE SUCCESS. THE MORE PROBLEMS, THE BETTER WE LIKE IT BECAUSE THEY KEEP EVERYBODY ELSE AWAY, HE SAID.
