What would actually happen if we had worldwide gender equality? Well, one estimate says the global economy would take off.
The director of the McKinsey Global Institute says there would be a $28 trillion boost to the global economy if women and men became equal overnight. That's nearly 1.5 times that of the United States' current economy.
Researchers studied what would happen if women were as economically involved as men. They looked at factors like job opportunities, leadership positions and wages. The World Economic Forum estimates globally women won't be earning the same as men for another 118 years.
But if countries focused on being as equal as the nation in their region with the least inequality, the boom could still be high, the director also said. We're talking $12 trillion or the total of China's current economy.
