That was a very different situation. The USSR was still catching up in industrialisation, and despite its huge losses still had vast reserves of labour in the countryside to tap. It was much more like the process of industrialisation in China that’s seen huge growth there over the last generation. Russia has already industrialised so it doesn’t have a catch-up growth opportunity in the same way. They are much more labour and resource constrained these days.
