1950 was after 40 years of commies take over Russia.
1950 was right after Russia lost 20 million of their best people of most productive age to stop nazy.
1950 was right after most developed regions were destroyed by Nazy.
Did not you learn in school about World War II?
Did you not learn in school about economic development of Russia during 20th century?
Figures went like this: 80% of population employed in agriculture (yes, even before Lenin made his putsch), majority of population was illiterate, more than 1/2 of the investment capital from foreign sources (exactly those which Lenin stole, feeling "no need to accept liabilities of former government")
But it is really nice to see this chart it actually shows what Russia capable of.
Because after all this in almost no time Russia sent Sputnik sent Gagarin and compete with US as an equal!
That is absolutely untrue, USSR (unless of course you believe false figures provided by propaganda), not even with their satellite regimes, never matched the US economic potential.
Second chart more interesting... It was not about richest country really, not about country which feed entire Europe at that time with wheat and oats. It was not about country which liberated Slavic from Turks all over Balkans. It is about speed of industrial Revolution which as I remember commies shows us on History lessons to show how great their ruling are and how they bring Russia from poor to rich - is your chart form same source? Whatever... This speed of course as in any race may vary until it settled down. And US pay for this speed later with great depression - as you may now.
It mainly shows how much provincial Russia was. As you know, NEP, following the wartime Communism when Russia almost collapsed, brought some vitality thanks to inclination to market but this ended in 1927. Then, the figure increase, was due to so called "Socialist industrialization" building heavy industry and GOELRO plan for all costs (like famine in 1931-1932). But in 1938, speaking in terms of industrialization per capita, the Russia still got only 38% of Great Britain's level in 1900 (moving from 15% in year 1900).
Is this somehow in accordance with your idea of the richest country in the world?
Now the cause of Great Depression was too high speed of industrialization? Hmm, really? What about credits issued to (almost) anyone, combined with small banks (or in better words the improper structure of the whole banking system) that were not able to accommodate the risk of default, imposing trade barriers (which turned to worldwide trend) or inactivity of FED?
Anyway production potential here shows not richest country, but country which most actively preparing to war - like Germany or most industrialized country like USA - which were on top of technological revolution sanks to Edison and Tesla, but again not richest.
What are you talking about now? FYI USA were on top due to capital and natural resources abundance AND high productivity, which was the result of much higher use of machinery (due to not so much abundant workforce as in other countries).
Do you really think the Russia was the richest country in the world? Or atleast what would today be called "developed country"?
And as for preparing for war - try to find out something on Stalin's plans for invading Europe. Russia WAS preparing for war...
I don't really know why I'm arguing with you. Go to the library and spend some time learning the facts. I won't continue in this.
