True in principle, but one may question the magnitude of the effect when the overall investment is rather low and/or short-lived.

There may well be tiered thresholds at and beyond which there are large leaps in ROI ratios. The trick then is to optimize between potential ancillary ROI and more direct investments or maintenance in other areas of state remit, most commonly infrastructure and social welfare benefits. In fact, though, one could also argue that similar ancillary effects arise in a similar manner (i.e. tiered thresholds) in such cases as infrastructure or welfare spending, which adds multiple dimensions to the equation.
