"The rich get richer and thepoor get poorer."

From reading "The Rich Get Richer and the Poor get Prison"
I do agree with the idea that there is discrimination towards the poor and African Americans.

Does this mean that poor people cannot slip out of punishment, but rich people can?

The essential notion of the knowledge gap is the proposition that a discrepancy exists in the knowledge that people of varying socioeconomic levels attain when engaging mass media content. In other words, the information-rich get richer when reading newspapers or watching television news reports, whereas those with relatively less background knowledge typically gain information at a comparatively lesser rate. The knowledge-gap hypothesis, explicitly formulated by Tichenor, Donohue, and Olien in 1970, goes beyond suggesting a simple knowledge difference between those with more and less formal education. What the hypothesis suggests is not just that there is a gap in knowledge between groups but also that this gap in knowledge widens as more information enters a society. The knowledge gap hypothesis has stimulated communication research in the United States and elsewhere since 1970. So far, researchers have published more than one hundred studies directly considering the knowledge-gap notion, and scholars have widely cited knowledge gap research in many different disciplines.

Everyone has a reason for being poor or being rich.

Explains the Tichenor-Donohue-Olien team’s general research paradigm and how the knowledge gap hypothesis developed. The book discusses the relationships among social conflict, citizens’ media use, and people’s knowledge, based on data from nineteen different communities in Minnesota. Chapter 7 directly discusses the knowledge gap hypothesis.

AB - There remains much unknown about how large-scale neural networks accommodate neurological disruption, such as moderate and severe traumatic brain injury (TBI). A primary goal in this study was to examine the alterations in network topology occurring during the first year of recovery following TBI. To do so we examined 21 individuals with moderate and severe TBI at 3 and 6 months after resolution of posttraumatic amnesia and 15 age- and education-matched healthy adults using functional MRI and graph theoretical analyses. There were two central hypotheses in this study: 1) physical disruption results in increased functional connectivity, or hyperconnectivity, and 2) hyperconnectivity occurs in regions typically observed to be the most highly connected cortical hubs, or the "rich club". The current findings generally support the hyperconnectivity hypothesis showing that during the first year of recovery after TBI, neural networks show increased connectivity, and this change is disproportionately represented in brain regions belonging to the brain's core subnetworks. The selective increases in connectivity observed here are consistent with the preferential attachment model underlying scale-free network development. This study is the largest of its kind and provides the unique opportunity to examine how neural systems adapt to significant neurological disruption during the first year after injury.

Support for the rich get richer hypothesis ..

Networks often show power laws. They can be caused by the "rich get richer" effect, also known as "preferential attachment," where nodes gain new connections in proportion to how many they already have. That means some nodes end up with many more connections than others. The phenomenon is well known, but had been assumed to be just a fundamental property of networks.
