Cultural development? Do you think about Prolet cult (Proletkult)? Proletkult - Wikipedia ))How exactly ? Modern Russia can't match Soviet Union in terms of Industrial capabilities, scientific development, cultural development, political and international influence, natural and human resources. The only 3 things Russia has over USSR are economic liberty, open borders and more liberal press. However, even economic liberty is seriously limited due to heavy involvement of the government in 70% of Russian economy and the press is currently in Putin's hands.
The sanctions are really laughable. Russia never had to face the same challenges as Soviet Union. Even the 90s weren't that bad compared to 1918 - 1922 period and bloody Civil War in former Russian Empire. Then USSR managed to achieve victory in WW2 and fought against USA (the biggest economy in the world) for decades. Soviet Union lost in the end, but it was a real war in all but direct military confrontation.
Soviet Union was also more successfull in terms of sports.
Even the V4 countries were more relevant during communism than now (In the terms of share in global GDP)
