Why are homes in Italy and France gated?

I've never seen so many houses with solid metal gates as Italy and France. Nearly every house has a metal and often, automatic metal gate. It's not like that in the USA... we have wood fences at most except for the exceptionally rich.

Is this the effect of socialist policies, gun control, inability to manage criminals or trespassers?
