As i wrote back in 1 of March of 2018:
“Europe needs not only hard
science research (and already has a lot) but also soft science in order to curb
the 1 Trillion tax evasion, reduce inequality, reduce poverty but more
important to help build a new and more cohesive social structure with empathic
and sustainable values”

P,.S - And let´s not forget the paper by German researchers (Krieger & Meierrieks, 2019) that connected terrorism and inequality https://pacheco-torgal.blogspot.com/2019/09/2019-paper-by-german-researchersincome.html meaning that USA high inequality is creating a future generation of American terrorists
