The answer is the following: in iucturā multōrum ("at [the] expense of [the] many").
Here is a brief explanation:
1) iuctura is a noun meaning "loss, sacrifice" which is the general idea of the application of "expense."
2) The preposition in with the Ablative can mean at specifically as it refers to a specific time or moment within. In this case then, in jucturā is an Ablative.
3) multi, -ae, -a is an adjective meaning "many, large amount." In this case, the adjective is functioning Substantively which means that the Adjective is standing in the place of a noun (Ex. "Blessed are the meek..." here "meek" is an adjective meaning "meek ones/people," thus it is functioning Substantively.). In this case, I chose Masculine Plural Declension -ōrum; however, it can also be Feminine Plural (-ārum) if you prefer.
Hope this helped!
