May it was surprise for you or for me, but not for experts from CIAs, who worked on it.
...Problems of USSR wasn't very secretive, I lived in this period and simpple walking by shops in Moscow in other town could give all demanded information for common people, and for experts.
...Colapse of USSR was inescapable after oil price was drop ... now the same situation can be with Russia.
You can read about it https://en.wikipedia.org/wiki/1980s_oil_glut (and it wasn't withouth paricipating of CIA)
In early 80s very few people predicted Soviet Collapse. At least by 1991.
AFAIK some experts did but the majority thought it would collapse later.
It's like the 2008 collapse only a few saw it.
I read that probably in the 90s. I mean the west knew about food lines etc but there were still a few closed cities and a lot if the Soviet hinterland was off limits.
Outside of Moscow, Leningrad and maybe Kiev not that much was really known about the internal Dynamics.
