Using ってことで to end a sentence


> 俺の夢はーー
>
> 遊「公務員かホワイト企業の正社員だ」
>
> 理々「それは夢ではなくて、安定なのではないでしょうか？」
>
> 遊「なら、安定が夢 **ってことで** 」

How should I understand the phenomenon of using ってことで to end a sentence? How
is it different from just だ?




Judging from this question and another question you have posted, I can see you
are having some trouble with 「で」. 「で」roughly functions like "with"
semantically and syntactically in these expressions. Sometimes "with" alone
doesn't quite cut it, but with a few more words, can render this expression in
English.

「じゃあ、そういうことで」：With that (said/settled), let's call it a day.

Similarly in your quoted line, 「ってことで」also concludes the conversation or
settles that slice of an exchange. More or less something like this:

> [My dream]
>
> 遊: civil servant or full-time employee at a good company
>
> 理々: That's not a dream! It's just a stable plan.
>
> 遊: Okay, my dream is stability then!
