I can't help but think from a scientific perspective that when a population is forced to fight for resources, aggression in that population also increases.
In the most basic terms, how would you expect a colony of mice to react in a scenario like this? A dwindling supply of food, along with a shrinking supply of shelter... I'd expect to see a steady increase in violence over time.
I can't see this ending well, and I certainly have felt a steady degradation of hospitality and compassion in the last decade or so.
Is there even a way to combat this? I feel like the cultural zeitgeist has been so polluted with individualism it's almost impossible to get the general public to agree to policies that don't directly benefit themselves.
