>IMHO all these “expenses” (using the first word that came up to my mind) were meticulously calculated after doing anything which means that the subsequent benefits will be much, very much more than that.
Not necessarily. Another possible explanation - I will not explore, right now, the probability of this actually being so - is a large expense for the country, combined with a relatively small profit (but still in the millions or billions) of relatively few individuals.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
