I have no idea how you did the gymnastics necessary to say that capitalist power structures that existed for decades before the USSR came into existence are modeled after it instead of the other way around.
Now I went to the western side of the Iron Curtain and see that actual, real life capitalism is not how "they" taught us it would be. It doesn't contain much of the bullshit that was created in our countries to be more capitalist. It is the same stuff we grew up with and that we know that it works. Just here it has a "capitalist" label attached, so nobody thought they need to destroy and replace it.
So yes, from my perspective it's socialist, because the capitalists told us that it needs to get replaced when they arrived in our countries. In fact it's just normal human behaviour.
