Disagree. You're falling prey to savior complex, so instead you should "Get out and get powerful and come back to be a hero" Translation: Go make fuck you money and then change what you independently determine is important.
You're wrong, because you'll have no idea what barbells to move when you come back, you'll just throw them around without purpose, like a meathead in a gym. Even so, not many people can move a 500lb barbell by themselves, but you get a few people around you you can trust, and 500lbs is pretty light. Much lighter if y'all can work together to break it down and take some weight off the bar before you move it, too.
You go away and get powerful, make some fuck you money, sure, you can buy a few houses, or support a policy or something, be a savior. You can toss a few barbells around with ease.
But if there's no buy in from others who trust and understand your motives, your effort will die. You might get your name in the record books for the barbells you threw, but there wont be lasting impact.
Just to clarify since I was unclear apparently, it isn't about returning to be a hero with no clear conception of what to do. It's all about having sufficient power to overcome inertial force so that things don't revert to what they were when you die. It doesn't have to be monetary.
The peer responses of doing this as part of a community are meaningful alternatives. I don't think that technique would work for me, but that technique may well work for others.
For one, OP didn't provide context but it's plausible they grew up/spent a significant amount of time in this city already.
It seems pretty clear that the GP was suggesting an alternative path to gaining influence/money/power, and it's not at all a given that 'getting your name in the record books' 'won't have a lasting impact'.
