LONDON (Thomson Reuters Foundation) - Women in developed countries are now more educated than men, yet they still earn less, are poorly represented in politics, and less likely to join the top ranks in business or become an entrepreneur, a global think-tank said on Wednesday. From Canada, Japan, Norway to Australia, young women on average earn almost 15 percent less than men, even though they are more educated, said the Paris-based Organization for Economic Co-operation and Development (OECD).
