Buffett, the chairman and chief executive officer of Berkshire Hathaway and the fourth from the top on Forbes Magazine\'s list of the richest people in the world, did not \"expect or desire,\" a raise this year, the company said. He even paid Berkshire Hathaway $50,000 0ut of his own pocket last year for personal expenses such as stamps and other office items, The Wall Street Journal reported Saturday. The bulk of Buffett\'s personal fortune comes from his personal investment portfolio, the Journal said. His salary at Berkshire Hathaway has not changed in decades.
