Okay, let me explain socialist accumulation to you like you're 5 years old.
So, you know how when you get money for your allowance or a gift from grandma, you can save it up in your piggy bank or spend it on toys and snacks?
Well, in a socialist system, there isn't really a piggy bank or a choice to spend money on whatever you want. Instead, the government or society as a whole decides how to use the money for everyone's benefit.
Socialist accumulation means that instead of individuals or companies owning and keeping all the money they make, the money is pooled together for the good of society. This way, everyone can benefit from the money and it can be used to improve things like schools, hospitals, and public transportation.
Think of it like sharing your toys with your friends. You give up one of your toys so everyone can play with it and have fun together, instead of just keeping it for yourself.
That's basically what socialist accumulation is all about - sharing resources and money for the good of everyone, instead of just a few individuals or companies.
