The more corporal punishment, the lower the occupational and economic achievement. That indeed is very startling. Research shows that the amount of physical punishment people receive as children affects their income as adults, with college-educated people having the most reduced income. Straus said people who have high-level jobs associated with higher education need creativity and initiative and instead may feel hopeless and powerless if they were hit as a child. Another negative outcome of physical punishment is the aggression children acquire.
Parents often hit in response to children's violence which sets in motion a feedback cycle.
Hitting may stop a problem in the short run but not in the long term. As a child grows older, physical punishment becomes even less effective, he said. There is a greater chance that it will escalate into greater violence because the child learns to hit the parent back and call him or her names. Also, the more corporal punishment children receive, the greater the chance they will hit their siblings or, as adults, their spouse. Physical assaults to someone outside the family are related to the amount of corporal punishment as a child.
