The next example has rough explanations about means of production, it's best at explaining the origin and development of these doctrines.

Imagine Stalinism and Trotskyism as two identical twins. One of them goes to their grandparents' farm to live and the other one stays in the city.

Stalinism, the one that left the city to live in the farm grew watching how his grandparents struggled with everything every single day, learnt things the old school style, got beat when he behaved, etc. Eventually Stalinism had kids and the grandparents passed away. Stalinism learnt everything about the farm and about general things from his grandparents (let's call these grandparents Marxism-Leninism and he does not know any better, so he'll force his doctrine and way of seeing the world into his kids, maybe it's not the best way of managing the farm but hey, someone has to do it somehow... The only difference? Stalinism starts consuming farm product instead of selling it, by doing this they stop having money but they start eating better, they don't really need to go downtown to get groceries nor anything because everything they need is there, in the farm. Stalinism also decides it's a good time to pull his kids out of school and homeschools them. As this happens, kids know something is up but they won't say anything: they do know better. But Stalinism starts being worse at parenting, beating kids for stupid reasons or for no reason at all, grounding them, being generally angry and controlling what his children (and not so children) do, read, watch on TV or hear on the radio. Kids know something must happen but they do nothing still.

Then the chickens start dying at an alarming rate. Cows and sheep don't make milk anymore, some horses scape, the freezer stops working and all the meat spoils... Everything looks bad for Stalinism's family, doesn't it? Well, not really. One of Stalinism's daughters marries a very rich businessman, that helps Stalinism buying him a new fridge, buying groceries each week from Walmart, et cetera. When you thought this would start smooth sailing, Stalinism dies and his daughter's husband moves into the farm and after some time he turns it into another Wal-Mart.

Trotskyism is a whole new story. As she stayed at the city, her education was formed by seeing how democracy and culture didn't got in the way of communism, but made it better, she thought communism was about unity, about stuff being in constant change and constant revolution... Which wasn't something compleeetely possible, but hey, everyone can dream. Trostskyism then spread to the world, without thinking about keeping it inside its house, because communism was something for all, that should be by all. To give a little bit of context on how was the social aspect, Trostskyism would've been some of those moms that only talk to their kids when it's completely necessary, but makes sure they have anything they could ask for and that they're in contact with friends. Like a cool mom, but not really. For trostskyism, revolutionary class and working class weren't the same, so some of their kids were treated as the focus and some others as a mean to make the focused kids look and do better.

But it didn't happen. Trostskyism is theoretical at most, never actually applied to any government because of its global characteristic, the fact that it only works if you do it worldwide and not in only one country. It's the kind of communism you'd like to work, but it doesn't.

It's pretty late but I'll get back later in the day to elaborate about Maoism. I've pinned this post for myself.
