If that's leftist economics, well, hell, I don't need to go any further.
It's not, anyone who knows a bit about the Russian revolution also knows Lenin and friends were the hard right of politics back then and totally out of line with mainstream socialists. (mensheviks)
Even Karl Marx himself warned of fundamentalists using the term "dictatorship of the proletarian" to twist into a literal dictatorship party.
The fall of the USSR was a triumph for Socialism regardless of the bitter taste it was medicine greatly needed since 1917 for the left.
The fact is righties here in the USA loved to call USSR Socialism to discredit Socialism as it was a crap dictatorship over there, and of course the Bolsheviks wanted to call it Socialism as it has a positive image to the working classes to hold power.
Sorry to rain on your parade, but the right wing generalizations about Leftist history are just that, stupid generalizations that sound good for the uneducated on a rather obscure subject in the USA for power.
The real world is a lot more complicated the Russian revolution doubly so.
How can you categorize "Leftist economics" back then when the Bolsheviks came to power they were challenged by a huge number of parties from the left.

The Bolshevik right wing hardliners did NOT represent the mainstream Left. All these folks in the parties listed above got put in gulags. You know, the actual lefties, the libertarian lefties being some of the first. Same shit as Hitler was doing to his actual lefties.
V Lenin wrote like 2 good books when he did a 180 and tried to be libertarian left to garner support for the Bolsheviks around WW1 time. When he gained power in the "coup" the mask came off and he went right back to right wing BS lefties hated him for turning the peoples revolution into a giant slave camp. -Once again reinforcing what old Comrade Karl (and Marx's rival Bakunin) were worried about in the 1860s.
When you associate lefties with Bolshevism it makes you look really dumb. We have far more reason to despise the traitors of the revolution then righties do. There are endless books going back to the 1800s warning people not to interpret Marxism as undemocratic as it defeats the very purpose of Socialism being based on social equality and personal liberty. (you know, actual liberal stuff) plenty of governments made it through the USSR bs and developed into benign mixed market economies that have even higher standards of living then the mixed market USA. Take the Bolsheviks fail of Russia (which Marx said would happen if Russia became the "leader") out of the picture and Socialism is fine and well across the world and actually settled into a mutual coexistence with capitalism without the violence that the Bolsheviks swore was necessary quite well.
But Socialism is really a scientific theory not a static economic system (google Dialectical Materialism) and is always evolving with the species and our ever changing history for good and bad.
Socialism can be seen to rest on the following principles:
1. The basis of human society is how humans work on nature to produce the means of subsistence.
2. There is a division of labour into social classes (relations of production) based on property ownership where some people live from the labour of others.
3. The system of class division is dependent on the mode of production.
4. The mode of production is based on the level of the productive forces.
5. Society moves from stage to stage when the dominant class is displaced by a new emerging class, by overthrowing the "political shell" that enforces the old relations of production no longer corresponding to the new productive forces. This takes place in the superstructure of society, the political arena in the form of revolution, whereby the underclass "liberates" the productive forces with new relations of production, and social relations, corresponding to it.
So there it is, if righties got through that post you should know your "enemy" better instead of listening to your own sides biased view that goes back 100+ years of silly accusations from the ruling classes and their media. Knowledge is power.
