Grudgingly, I will accept only half way measures to point you to one possible way. This time, the chips will be left as they fall.
Circa mid 1980's Yugoslavia was a fairly centralist economy socialist/communist country. Partly, some free market did exist. For example, a huge RV went across those countries to Moscow and back. Since leaving the west, the first they found scouring powder (Comet, etc.) was when almost back, while in Yugoslavia. It was low grade diatomaceous earth in very lose powder form.
Tito, of course, left the USSR orbit because of assassination attempts courtesy of Stalin. The west was overjoyed to have a kink in the iron curtain, a thorn in the side. There were still some purges, but on a lessened form. There still were large numbers of people fleeing to Austria -- until about 1960.
Then Tito was advised to open the borders. Why? Because he apparently was told that what would happen is Italy/Austria (and Australia, the main goal of most would be emmigrants) would be forced to adopt their immigration policies, as turned out to be the case. And flooded with other applicants, huge waiting lists were the norm, like a decade. I have personally met devout socialists railing at the 'decline of socialism' while in mining towns in Australia's outback, 7 years ago.
One POD a couple of weeks ago asked for similar methods. I suggested if, repeat, if Tito swallowed his pride and pulled a Franco (reinstitiution of the Monarchy), there would be a chance. True, as another pointed out truthfully, Serbian monarchy was extreme, but it would have helped.
Also, breaking up to multiple grades of capitalism, the obvious of Slovenia on the fast track, would have also helped. Still we would have seen a Italian style North/South issue, perhaps with a some what dead center of Serbia (present day Macedonia is on the border with somewhat affluent Greece, but there could be problems still). Or India, with its economic powerhouse South and more traditional North.
