That one comment right there distills Marixist, collectivist thought. They decry the human animal's desire to improve one's condition. For as long as that desire exists, then collectivist control is not workable.
The desire to live comfortably, to provide for one's family, to want better for your progeny - the Godless Marxists cannot abide it.
These kulaks are exceeding their resource ration. They must be repressed.
