In this modern world, there is nowhere for the common folks to fish for food. Every pond, lake, and sea is owned by some rich person, organization, or government.
One big fear is that technology is making many jobs redundant without creating enough new jobs. For example, companies are experimenting with drone delivery. Imagine the number of delivery jobs that will be axed. Other companies are coming up with driverless cars. Soon, taxi drivers and Uber drivers will have to team up to protest against robotic drivers.
