Sure ain’t clear to me: this link to a Wired report on whether wealth makes people unethical. For example: not at all clear that wealth is not “caused” by some personality trait (which could be genetic or caused by upbringing) that also tends to “make” one unethical. In which case the headline: “Wealth Could Make People Unethical” is completely wrong. The headline would read, in that case, “Genes (or Upbringing) Could Make People Unethical.” Very different.
It strikes me that this paper is mostly an attempt to incite class warfare.
Somebody needs to whack these social “scientists” on the head with “C or C”-stick. A big one.
