I've actually heard a far more accurate version of the statement, given the actual workings of a Marxist economy in a communist state:“from each according to his ability, in service to The State, to each according to his needs, in service to The State.”
Remember, "The Good of the State" is the ultimate goal. Don't ever let anyone tell you that "true communism" has never been implemented. It's been in use for eons... Look at an insect hive society, primarily an ant or bee colony. That is the "perfect" communist implementation.

And the hive mentality is the end result sought by the “Progressive/Liberal/Leftist/Socialists”.
