Speed and size of immigration has real world social integration impacts in Sweden. A story I was told: after one refugee crisis, some refugees ended up in Sweden, some in Minneapolis, US.
(From chatting to a handful of Swedes)
The narrative I heard was that the refugees in Minneapolis (on average) have integrated better (in a shorter time) as more of them had to seek jobs and employment helps social integration (although given time, integration and jobs can be achieved in Sweden). Whereas the refugees in Sweden didn't find / weren't forced to seek jobs under the same type of pressure - This recalls to me psycho-social studies that show working together in increases harmony (esp re: race) - a whole set of studies and questions found here at the Oxford Centre for Intergroup Conflict.
It is also anecdotal evidence in support of a job guarantee policy idea as suggested in a paper by James Montier (see GMO site) and by the left libertarian mmt economist Bill Mitchell (see Bill’s blog, with comprehensive left libertarian economic thinking, an advocate of Modern Monetary Theory).
This idea is potentially stronger than universal basic income because a job gives you skills (both intangible, and measurable) and experiences plus can promote social harmony. Still, there did seem to be broad hope that given time, the new Swedish immigrants will also integrate. The newly arrived need to learn the skills, language etc. to help them find jobs - there are seemingly many who arrive unable to read/write well and that’s a problem.
The anecdotes I heard were not studies. I found a study here and an in depth reporting here on the issues, the two pieces did seem to align broadly with what I heard, suggesting some Swedes at least are abreast of the issues.
If you'd like to feel inspired by commencement addresses and life lessons try: Ursula K Le Guin on literature as an operating manual for life; Neil Gaiman on making wonderful, fabulous, brilliant mistakes; or Nassim Taleb's commencement address; or JK Rowling on the benefits of failure. Or Charlie Munger on always inverting.
