I think we have what is known as "culture lag." Our population has grown to the point that we are crowded all the time; our cities are bursting at the seams; our schools have overcrowded classrooms, etc., etc., etc.

Culture lag results from the culture not adjusting quickly enough to changed circumstances. So our cities are still primarily the way they used to be when populations were smaller; our transit systems haven't changed enough to accommodate the greatly increased traffic; a lot of our children still go to schools that were built to accommodate much fewer students, etc.

So we are all on top of each other, causing pressure, stress and temper -- we need our space.

Until our cities catch up with the population, in terms of infrastructure primarily, I think violence may continue to be a problem.

Just an opinion. Don't hit me.
