Under Putin, Russia has only managed to rebuild part of the industrial infrastructure that they had in the soviet era. And while it's true that Putin's political father had dismantled the soviet industry, stealing everything that wasn't nailed down, and bringing heavy crowbars for what was nailed down, Putin has had enough time to do it. He didn't.
Not because he doesn't want to, but because he decided to spend Russia's energies in futile and criminal little adventures like Chechnya.
Gorby's plans were working. The dreadful economic state was how Brezhnev had left it, which is why the CPSU was willing to place an aperturist as General Secretary, and under Gorby's aperturism, liberalization and democratization, the Soviet economy was recovering quickly. The Soviet Union could have been the "China" before China did it itself.
