That's a remarkably moralistic and simplistic view that ignores the realities and mechanics of large-scale power. Simply LARPing as though we're world-changing with our banal existence isn't helpful, it's pure self-indulgence.
Unless you're very wealthy, very violent, or very committed to a cause (often to the point of entering politics or raising/moving money) your individual contribution is negligible.
Individual contributions may be negligible at a large scale in the short term but they have the potential for global impact if you give them enough time, not talking about a few years but generations.
An uneducated mechanic and his wife decide to give an unwanted child a home, dad builds a workbench for his son and teaches him how to use tools to break, fix and build things, inadvertently setting in motion the beginning of Apple.
Sure, there were other events Jobs parents had absolutely no control over, like those that led Bill Fernandez to the same school as Jobs.
But it is undeniable that without Paul and Clara Jobs adopting Steve there would be no Apple and the world would look completely different today.
So through our small, individual contributions we can definitely nudge the world to follow a particular direction, and if enough people do it, it is expected that once in a while one of us actually ends up changing the world.
