there are times when you have to use force on children, for exmple, grabbing them if they are about to stick their hands in a socket or something. But generally, using physical punishment, will teach them this is a legitimate way to solve disputes. Studies show that children who receive corporal punishment are more likely to engage in violent, anti-social behavior as they grow older. Talking to your kids and having them understand WHY they should do or not to do certain things will not only set a better example, but make them more responsible since they learn to do things because there's a reason to do them, not for fear of punishment. It will also increase their critical thinking skills if they feel free to question and understand what the rules are, and why they are there. It will improve the parent-child relationship; the child sees the parent not as an arbitrary authority figure, but a caring and thoughtful person. Hopefully, it will also break the connection between takes care of me/punishes me, which the government exploits.
I don't think it's a complete coincidence that poorer communities see higher rates of physical discipline correllated with greater cmmunity violence and dependence on the government.
