Firstly, GDP growth -- this was purely due to oil price increases
GDP per capita -- again, the same thing, it went up with oil and gas prices, not with any value add from Putin policies
==============
Look at Russia's GDP growth year on year -- it never exceeds 2%, which is lethargic for a developing economy
This is because he has wasted the potential of his people - the smart Russians have left Russia and work in the West. The GDP growth is purely due to using Western machinery to extract stuff from the ground and sell it.
The tragedy is that Russians are smart and they could have developed an economy, but Putin and his oligarchs have not given them a chance to do so
What is the proof that the growth in GDP has been purely with extracting stuff and more so with just lining the pockets of Putin and his oligarchs?? -- look at the poverty rate in Russia
The poverty rate reduced during the commodity boom, but after that, they have NOT improved -- compare this with that other authoritarian regime, China and see how China has invested in its people (it's still an authoritarian regime, but it has realized that growing its people is a good investment - Putin didn't do that)
But don't mention the next 3 years
Social inequality in Russia is en par with Nigeria
Now I know little about the people of Nigeria, so can't comment on them, but I do know Russians, all except one fled Putin - and they are smart, hard working people. Note - they fled Putin and work elsewhere.
