Again, absolutely zero evidence is provided to back any of these claims up. Researchers who have actually bothered to put in the work generally say that, in reality, these figures were the most accurate of them all, that they were honest efforts to catalogue and plan for the Soviet economy. These were not "articles on artificial fulfillment of plans", because that would imply they were published for public consumption. They were not. They were regarded as state secrets and to publish them even for domestic public consumption was verboten.Which is as bad if not worse. One reason that the Soviets had so many problems is everyone lied to everyone else. Even at the time there were articles on artificial fulfillment of plans. The various enterprises all lied on their production numbers so that they could fulfill their plans. How can you rely on data based on lies?
Even leaving aside the veracity of your claims, the problem with saying all figures ever used by honest academic research into the Soviet economy is are false means the Soviet economy is impossible to empirically research and thus your original claim is not provable nor is it actually made based on any hard evidence. I can just as well claim that this means the figures are actually wild underestimates and that the Soviet economy actually hugely outperformed the western and was the bestest ever and I’d have just as much of a leg to stand on in the empirical data.
One might try to turn to anecdotes in this case, but that honestly doesn't help because one can often find similar such anecdotes in the West. Turns out that things like fraud, destitution, and socio-economic backwardness happens in the west too, but at least there we have the data to give us an idea of what the scale is and whether, thus, things are better or worse then in the Soviet case. Or not, as the case may be, since apparently all the data we have on the Soviet case are wildly inaccurate, lies, or both according to you.
Dismissing all figures that contradicts their claims as “lies” without any demonstration they are, in fact, lies while showing absolutely nothing to back up their own claims up is the picture perfect image of an ideologue talking out of their ass.
So basically you won't accept any evidence that doesn't confirm what you already think about the Soviet economy.
