We don't have to overtake or even match, we can just operate independently, even if technologically somewhat behind. I don't know the standard of living of my equal in China, nor do I need to know. It's only necessary for me to be happy with mine in this world of inequalities.
As for relative size, the ruling and emotional heart of Russia has always been in Europe, and it would be very easy for a United Europe and Russia to unite as one. Indeed this is the German political preference, which is why they've opposed the current sanctions, preferring diplomacy. The combined whole of Europe and the Russias of near a billion people would be a match for any other of the world's giants, its vast area also.
We just have to think smart, be open minded and see the possibilities.
