The Miljonprogrammet was before the wave of arrivals, from the analysis I read (please don’t ask me for a source it’s been years) the initial problem areas were actually new green-field social housing projects, built way later while the older areas were run-down, but had a maybe precarious but not atrociously so socio-economic mix. The perfectly integrated immigrant kids there then found themselves de-integrated by their fellow Swedes, suddenly not part of civil society any more, as shit hit the fan among kids 20+ years younger elsewhere. And there’s only so much instilling of Swedish values you can do when the rest of your country turned your back on you, so a bunch of the older housing projects went from precarious to shit.

Anyhow the main point, the main issue, is still that Swedes, as a society, suck at complaining while considering themselves infallible.
