Some years back I hiked the Inca Trail in Peru. The second day started with a long trek up the side of a mountain, covering a vertical distance of about 1500 m in about 4 hours. You could see the trail ahead pretty much the whole time, including the people on it. It was incredibly challenging to keep going as you were exhausted by altitude and effort and could see it was only going to get more difficult as the day progressed, and still you could see the people who were already on the trail ahead of you. This was the point where many hikers turned back.
What I learned was challenges that defeat you are never what's behind you, only what's in front of you. When it's an uphill climb, the people at the top are causing more of a challenge than what you left or even where you are.
I frequently encounter the position that "we shouldn't do anything at my level because the problem is further down the system" just like the parent comment says. Yes, it makes you feel better to deny you're part of the problem. Unfortunately it's not true in a way that makes the problem worse. It's a close cousin to "she shouldn't have dressed like that" or "she shouldn't have gone out alone". Or maybe "I was just following orders".
