Rey's lineage is another example of the populist outlook of this installment of the saga. Kylo Ren tells Rey that her parents are nobodies, just drunks from Jakku, and that, accordingly she "has no role in this story."
But, once more, everyone has a role in the story. You don't have to have a name like Skywalker, or Kenobi, or Solo to be important to this galaxy far, far, away. Just like in real life, our leaders shouldn't have to be members of the Trump, Bush, or Clinton family to wield power.
The movie’s sense of populism extends to the awakened Force. A stable boy slave, like Rey -- a desert scavenger -- is sensitive to it. This is a metaphor for individual power in the political arena in 2017. So many people feel powerless today in America, unaware that they still hold great power as long as they make their voice heard (which, frankly, just got exponentially harder with the anti-democratic repeal of Net Neutrality).
