Every market economy where prices change experiences "massive shortages and surpluses of goods. Price changes are supposed to be
reactions to that. That shortages and surprluses are constantly happening is nothing unique to any system.
What the pure market systems proponents claim is that because prices adjust in a way to negate access to the goods in "shortage" to those who can't afford them, well the everything is jolly good! The shortage magically ceases to be a shortage because by definition what is unaffordable is not in a "shortage"! 
As for surpluses, that is something market systems are indeed very adept at not having. Even whatever was once free, if someone can figure a way to fence it off and sold for a profit by causing artificial scarcity, they will. "Intellectual property" was a child of just such "market thinking".
But let me tell you, the piece you chose from the wiki on the USSR' economy is rather interesting. Let me quite it here:
I can think of a great many "market economies" that recently experienced longer periods of stagnation or, as propaganda puts it, "negative growth", that 6 years! Does that mean we are witnessing the final days of those economic organizations? Of it only that were true! It would mean that and end to the "long depression" was on sight, that the power of the financial oligarchy was broken.
The USSR was not going through some terminal economic crisis in the 80s. The USSR was refusing to adopt the financialization model the west adopted, refusing also to embrace the "efficiencies" of the west. It distributed "too much" of its product to its workers, it spend too much on wars (something familiar?), it didn't embrace management with low stocks; JIT; delocalization; debt-financed trade; it didn't cut "inefficiencies" and built a "lean" economy. It other words, it was stuck in what the west had been doing in the 60s while the west was moving to the economic behaviors of the 80s/90s.
Well, we (the "western world") has had a good run for a couple of decades with those things. But, guess what, it is turning out that those models too have downsides and limits, that they too create and accumulate problems. History didn't end after all.
