When a society has a set of values it seeks to uphold, say derived from natural law, reason, and other things such as science or tradition, and it fails to uphold these values, and things collapse, then how is that not robbing from the future? If it isn't theft it is certainly negligence. I don't say that the solution need to be that the government does it, but the society as a whole needs to do it. Now, one can debate what these values are, and what the state of society needs to be, but it is still there. Part of that is to ask what the net outcome of certain things happening, like say homeless people dying in the streets, or crime running rampant, or a civil war breaking out, or even polution, with businesses creating poluted pools of toxic chemicals in areas accessible by the public. To not ask such questions on what the values should be and the net outcome of ignoring things, is negligence on the very least.
