I don’t think the turning long-term consequences into short-term ones is what’s vilified about spanking. There are other ways of doing this that don’t resort to violence.
- Taking away something that they like
- scolding them
- giving them a time-out
I’m not sure if they are as effective as spanking or not, but they can all be ways of turning long-term consequences into short-term ones, and I don’t think they are vilified the same way as spanking.
My point being that the violent part of spanking is what is frowned upon, not the making-consequences-immediate part.
E.g. your question assumes that spanking is effective in making the kid well organized and well focused, but what if that simply does not happen?
