I recently read a story on FEE.org that described the flaw in "thinking globally" (https://fee.org/articles/the-pretense-of-thinking-globally/) Essentially, coercive acts imposed on a people is automatically flawed as those in the position to impose such acts lack "the genius of the place" for the expectations to meet reality. Only the people in the "time and place", with local views, can make gradual adjustments toward a better tomorrow.
This thought goes hand-in-hand with the idea of the "Prosperity Pool" (http://cafehayek.com/2004/06/the_prosperity_.html). Real prosperity comes from the contributions of people improving their own lives through local decisions. The most obvious form of "thinking globally" or "making a big splash" is government policy on a federal level.
The best approach, in my mind, is a Minimum Effective Load strategy; minimal input with maximal output. In this situation I relate "minimal" with "local" and what actions can be taken to have a "maximal" effect or "global" effect. I believe everyone should become staunch advocates of public banking at the municipal level. By focusing our efforts on building strong local infrastructure and commerce, we also take away our dependence on corporate banks.
You may be thinking, "Why not just support your local credit union?" To that I say, "Absolutely!" Public banking; however, takes it a step further. Instead of a non-profit credit union built to provide better rates and lower fees to the public directly, a public bank's purpose is to support the municipality as a whole. Facilitating city investment, affordable housing, and credit to local commerce. Personally, I see the biggest role of a public bank as the ability to use the tax revenue the city receives as capital for the bank to borrow funds from the market, purchase bonds issued by the city, and return the interest accrued on those bonds directly back to the city! Typically, those bonds are purchased from large banks and the interest on those bonds are paid to them and leave the city.
If enough people begin to think locally, we can gradually take back the power from those thinking globally.
