To claim “Not enough” is the signal for something goes wrong

Background

I sometimes hear the “Not enough” in Japan.
Not enough money, not enough Human Resources, not enough time, and so on.

Why do they claim “Not enough”?

In their views, there are just suitable numbers for satisfying their needs or wants.
For above view, they claim “Not enough” to others.

My opinion

“Not enough” shows something goes wrong.
If this signal appears, we should check our minds.
Because our minds may tend to blame others or our environment.
Furthermore, when someone claims “Not enough”, he/she often blames others or environment to solve his/her problems with less efforts.
