Business Insider's US Editor-in-Chief, Alyson Shontell, asked Gates why she made that assumption about working women. Gates explained that she was raised in a middle class neighborhood in Dallas, Texas, where most women did not work. Her mother led a small real-estate business, but she was also home with her children.“I did have a role model of a working mom in a small business, but I didn't have a role model of a woman going off to work,” Gates said.She also said that because her husband ran one of the world's most powerful companies, she knew Bill would not be able to leave his job or take a step back in his career. Gates recalled saying to him, “If we want the values that we both believe in as a couple for the kids, somebody has to be home to instill those values.”That didn't mean Gates was done working outside the home forever.“Bill was incredibly supportive all along the way,” Gates said. “Even after Jenn, our oldest was born, he would say, ”What are you going to do？“ Because he knew that I actually enjoyed working, and that was supportive to have a husband say that...He knew that I would enjoy using my talents and my brain on something else in addition.”Once Gates' three children were a little older, her perspective on needing to be a stay-at-home mom changed. Though she says if she had to do it all over again, she'd still have chosen to quit her Microsoft job for her family.“Once we had the values [established and] we had people around us who were also imparting those same values that we had, then I felt, 'OK, I do want to work, and I will be a working mom.'”Read Melinda Gates' full interview with Business Insider, or watch below »Youtube Embed: //www.youtube.com/embed/BuYfALzDPrY Width: 560px Height: 315px
