Thinking that money is the last power we have is a defeatist view. Anyone who takes this view is saying they are powerless to the circumstances of their lives. By saying they have no power, they are absolving themselves from responsibility. The consequences of removing personal responsibility are vast and far more damaging.
Is money a power? Yes
Can consumers effect change? Yes
Is this the only power an individual has? No
We tend not to recognize our powers, not because we don't see them. But once admitted we then have the duty to use them. But with power comes responsibility. Which most people shy away from.
In conclusion I would like to leave you with a quote:
"Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. It is our light, not our darkness, that frightens us most. We ask ourselves "Who am I to be brilliant, gorgeous, talented, and famous?" Actually who are you not to be? You are a child of God. Your playing small does not serve the world. There is nothing enlightened about shrinking so that people wont feel insecure around you. We were born to make manifest the glory of God that is within us. It's not just in some of us, it's in all of us. And when we let our light shine, we unconsciously give other people permission to do the same. As we are liberated from our own fear, our prescene liberates others."
