There is a small village in Bangladesh where people just starve to death due to the lack of opportunities but one resident of that village decided to make a cooking/mukbang channel that focuses on Bangladeshi cuisine. After his channel got viral he decided to cook for thousands of people. He Pays the villagers to be butchers and cooks for the cooking channel. Then the families of the villagers gets to eat the food. A single dollar will go far in Bangladesh and this village is earning dollars on Youtube, So you can imagine how the lives of these villagers changed.
I think they just copied Grandpa's kitchen from India (A channel that feeds orphans) and decided to go for a village of thousands of people instead. Because of this Youtube channel the creator of the channel is able to not only feed the villagers but help them on their needs like medical bills and other emergencies. He wanted his unknown village to become a tourist attraction.
As long as Susan will not screw this village because of some stupidity from Paul Brothers/Pewdiepie/feuding Beauty Gurus/Elsagaters then this channel will continue to succeed.
