People who are in a state of long-term scarcity tend to be more aggressive.

When a person is constantly lacking money, opportunities, or a sense of security, their brain shifts from thinking mode to survival mode, leaving only three actions: grab, defend, fight.
Therefore, they are more likely to interpret neutrality as a threat, competition as hostility, and others' success as theft.
Scarcity creates a zero-sum illusion: your win = my loss, your gain = my loss.
They maintain their sense of position by negating others.
