The most through take on the issue is probably this string of comments by /u/commiespaceinvader.

And as I have noted in some previous off-hand comment;

[...] namely, economical crisis starting in late 70s into 80s, and utter failure to address it, specially under Duranovic-era, while there were influential works coming from non-government related individuals / institutions, that were critical of its handling, like Jugoslavensko društvo u krizi by B. Horvat, Kosovo unrests, perhaps not so much by themselves, but with a more broadly sympathetic sentiments to violently suppressed Poland protests in 82, and the parallels that emerged from this, and other lesser ethnical tensions, widespread censure, JLA, persecutions that publicly resonated, differences between the republics ( in factors enumerated ), literary revival and bringing into public discussions of post-war killings, Dachau trials, not necessarily as events in themselves, but in a more broad political significance, as we get highly impactful works on politology like Stranacki pluralizam ili monizam : obnova i zatiranje posleratne opozicije by Kostunica, we have new publications which sought independence from political overview, like Slovene Nova Revija, and so forth. As said, I would gladly expand on these specifics singularly if requested.
