There's a problem where intensity can easily slide into ruthlessness. Cultivating a society of impact that degrades overall flourishing seems like a bad recipe to me. Even if it works out for some by the usual measures.
In Buddhism, there's a saying: "though the view should be as vast as the sky, keep your conduct as fine as barley flour" - Padmasambhava. Having that attitude combined with an intensely focused engagement in building is an overall better path.
