That was an end to an erea. Nowadays the rules are to bring children up as pansies. The new rules have brought a lot of problems that didn't exist before. If you haven't seen how it worked before, then how can you judge which method works best?
One of the examples of change is guns in school. Some schools allowed children to bring guns to school. Show and tell. Target out back. Selling, buying and trading guns. Nobody was afraid of somebody with a gun. It was unthinkable to even think of shooting someone. If you think today's method of discipline is better it's time to pull your thumb out of your mouth. Because today's methods isn't working we have serious social issues, which includes killings in school.
I went to school in the intermediate period of time, where physical discipline didn't happen but the culture of total indulgence of children hadn't developed yet. Teachers had no issues keeping the class under control, and nobody went home afraid of authority figures. Seems like the best of both worlds, but it relies on the parents holding kids accountable and not just blaming the teachers for everything.
