Maids trafficked and sold to wealthy Saudis on black market
I once met a very bright young lawyer from London, UK. She had worked on human trafficking cases in the UK. And she was so shocked with what was happening in the UK and the apathy of governments across the world that she decided to do a startup to tackle this problem. It requires a lot of money and connections to get a project of this nature off the ground. She was hoping to get into YC. Was rejected. After few months of trying to raise funds she gave up. She once said to me that there are actually online marketplaces, similar to how Amazon is for goods, to sell humans!
