In the "Star Wars: The Force Awakens" teaser trailer two, Luke Skywalker says:
"The Force is strong in my family. My father had it. My sister has it. You have that power too..."
So how will the universe change when a means of letting anyone access the powers of The Force becomes available, rather than a few sensitive people who study and train for decades to become Jedi or Sith? (I mean the social, political and economic universe. While trillions of sentient beings could potentially rearrange the physical galaxy using the Force, this would require an extreme level of organization not being contemplated at this time).
It does not matter if you are part of the Empire, the Rebellion or live on an isolated planet that is not involved in the conflict, so long as you are a sentient being, with some relatively simple method you can access the power of The Force. Like all powers and skills, you still need some training or instruction to understand all the aspects of The Force ("The Force for Dummies"), and if you spend more time practicing, you get better at the attributes you do understand.
There will be a bell curve of ability, with a very few on the left tail who simply do not understand or have the ability to access The Force, and a right tail where the Jedi masters reside, but the bulk of the population now understands what The Force is and can manipulate it for their own ends.
