「最近【さいきん】の都会【とかい】にはお互【たが】いに面倒【めんどう】をみる『かまいあい』がなくなっちまったよな～」
The "Kamai-ai" spirit of taking care of each other has disappeared in the cities these days.

Could one write this word as 構【かま】い愛【あい】?
As noted in the comment, it is 構い合い although it is more of an improvisation and not a common word.
あい here is a nominalization of あう, suffix meaning each other:
Since 構う means to take care of/look after, 構い合い more or less means the same thing as the preceding お互いに面倒をみる(こと).
