I think people naturally extend their unresolved issues and the concomitant behaviors into the macro scale, and that it is precisely by resolving the personal issues on a smaller scale that you gain greater power over your own life. As you do, your methods and behaviors spread, because people learn well by example, particularly when that example "wins" and comes from a natural place of acceptance.
As people resolve their piece of the pie, they run into others who have, likewise, resolved their piece of the pie. ..and, together, they do greater things, because they are capable of it, not tangled an a huge ball of personal issues, and why not too something or contribute to something you want to see done in the world?
The massive issues we have a a society are precisely because we have too much emotionally charged information, and haven't processed that information - and because the blind spots you have in your own personal life and with your own personal issues become your cultures, your nation's, and the world's problems as you gain power.
Sorting through your issues, and resolving your blind spots means your power increases. And, as you do, then the scope of what you, personally can change grows - in part, because you are also more effective at working with others and rejecting (or similarly handling) problematic authority as you do.
This is just bad advice.
