It seems this moves in a circle-- the points system guides production, but there is no fear of "underandedness" because socialist production automatically produces enough for all.
He said there would be no "social basis" for underhandedness. Somebody is going to regret not ordering a commodity, and will buy, trade, or commit a crime to get it. That's not the same as, for example, systemic inequality that favors a high crime rate. It's more like forgetting to budget for a computer printer and then having to wait until you get paid again (your points are replenished) to be able to buy it.
"This is my test of character. There you have the despotic instinct of men. They do not like the cat because the cat is free, and will never consent to become a slave. He will do nothing to your order, as the other animals do." — Jean-Jacques Rousseau.
"The intellectual and emotional refusal 'to go along' appears neurotic and impotent." — Herbert Marcuse.
"Our blight is ideologies — they are the long-expected Antichrist!" — Carl Gustav Jung
