日本の医療はすでに崩壊している。 Medical care in Japan has already collapsed.

 開いた口が塞がらないというのはこんな事態で使う言葉なんだろうな。医師会長も政治資金パーティーを開いた政治家も同罪でしょう。

The word that the open mouth is not closed is probably the word used in such a situation. Both the chairman of the doctor and the politician who held the political fund party will be guilty.
