nope. the us for example had a much higher population growth than eastern europe. every western country continues to experience population growth. the population growth pre 1990 in eastern europe was at a healthy 1%. stagnation and negative rates started in the 90s, which was hardly a period of prosperity in eastern europe
> Countries that stagnated for 50 years went through a 10x growth in 30 years after the Soviet grip disappeared
tell that to everyone that dreams about leaving and working in western europe

in the mean time, here are some of my own

Despite its drawbacks, the soviet healthcare system (Semashko model) is considered by the majority of Russian experts to have been one of the best in the world, because overall it met the requirements of quality, availability and provision of healthcare services, drugs and materials. After the collapse of the USSR, the health-care system was stagnant: funding was greatly limited, highly-skilled medical professionals emigrated, medical research came to a halt and manufacture of drugs and medical equipment declined dramatically.
