[ WP ] A technologically-advanced alien race consumes the stress of other beings the way we consume oil ; they use stress to power their entire civilization . Facing a fuel crisis , they have just learned of the existence of planet earth .

They had come secretly, and set up their refineries. Humans were great stress producers and were easily incentivized to produce stress. The beat part was that they were so pathetic. So humans were herded into the refineries and made to stress. It was a mostly hands off approach as they wanted and would apply to work in the buildings. They called it work, filling papers, making deadlines, buying and selling from each other. They had to support others or their habits and lifestyles. The movement cascaded through their society and soon Earth became one of the biggest stress hubs in the galaxy. 
 
 
 EDIT: 
 
 
 It's been three days since I found out about stress extraction, my only solace is Meditanyol, a new experimental drug, I was on for my stress. Lucky for me, on it, I'm relaxed enough so that I do n't produce enough stress to feed the aliens more. It also lets me lie low enabling me to discover who the aliens are hiding as. Now I knew, I had poked around, and I should have known this whole time, Big Fat Cat CEO of this company, Allen Kittens. I had caught him and the president of the company talking about keeping the employees stressed so that they'd work hard and make more for themselves 
 
.... It was so obvious now!
