There's a split between delegates from developed and developing countries at the World Economic Forum in Davos this week: the former are pessimistic on their economies, while the later seem bullish.
The reason, according to Tom Speechley of $7.5 billion private equity investor Abraaj Group, is simple demographics.
"It's an inverted pyramid in the developed world and it's right-sized-up pyramid in the developing world," Speechley said in an interview with CNBC.com. "That's giving rise to consumption on a scale never seen before, and that's giving rise to a lot of optimism."
Founded in 2002, Abraaj invests in so-called "growth" markets in Asia, Africa, Latin America and the Middle East from 25 offices spread across hubs in Dubai, Istanbul, Mexico City, Mumbai, Nairobi and Singapore.
According to its website, Abraaj has returned about $4 billion to investors from selling or taking businesses public.
