In a speech at the World Economic Forum in Davos, Switzerland, the software tycoon plans to call for a "creative capitalism" that uses market forces to address poor-country needs that he feels are being ignored.

In particular, he said, he's troubled that advances in technology, health care and education tend to help the rich and bypass the poor. "The rate of improvement for the third that is better off is pretty rapid," he said. "The part that's unsatisfactory is for the bottom third -- two billion of six billion."

But Mr. Gates's argument for the potential profitability of serving the poor is certain to raise skepticism. "There's a lot of people at the bottom of the pyramid but the size of the transactions is so small it is not worth it for private business most of the time," says William Easterly, a New York University professor and former World Bank economist.
