Is that supposed to portray a typical rat lifestyle? Like in the wild rat colonies are always governed by human's garbage supply schedule..

We didn't know what they were. We knew they weren't musk rats. We called them "river rats". We knew they could get big. We mostly saw them in riparian areas--- great swimmers. We never saw black rats in the suburbs.

Every thinking creature requires a 5th Element: Validation Breeding - creating children - is a method of acquiring validation. Quite simply, people have children to feel more valid. When a culture offers other methods of developing validation - offering other methods of creation - a society will breed less and seek alternative methods of acquiring validation. For example, Japan has offered its people many alternative opportunities for creating personal validation outside of breeding. Thus, the population of Japan has fallen at precipitous levels. In summary, simple people in a simple culture breed to feel validation. More sophisticated cultures offer alternatives to breeding that elicit personal validation resulting in a decline in population.

Ah yes, many alternatives to validation such as "working full time your entire life and ending up in poverty", so much validation that must be why they don't have families

Yeah most people that do t have children actually wanted to have Children. So your inference is off in my opinion

I'm sure some people have kids for validation or other reasons but, generally speaking, humans are built for reproduction so reproduction is just our natural inclination... not something done for our ego or whatever. Having a family of our own (rather than just making babies & moving on to the next asap) has been ingrained over thousands of generations and only recently is it becoming something that's not expected as a natural part of growing up & where any noticeable amount of people are moving away from that (it's a relatively small amount of people).
