Except the next generations can't time-travel snatch the current population: Technically it can put aside money while it operates: this either makes it somewhat scarce now to the benefit of current capital holders, or this encourages injection of fresh money by the central banks. Then if in a few generations away something goes wrong and the stash of money is released it devalues money by buying up labor manhours (thus making manhours scarcer for all the holders of capital in the future).
