“press X to doubt”

in my understanding, relying on wiki for definitions:

communism is stateless moneyless propertyless religionless classless society where there is the common ownership or non-ownership of the means of production

socialism in theory wants to prioritize the value of labor and seeks to have the common social democratic ownership of the means of production

in that there are hierarchical meritocratic levels of achievement?

or that there are extractive processes which benefit the top at the expense of those lower?
