Not only do we put up with it. Many don't know anything different.
When I tell my kids I grew up in a not so great, working class city in upstate NY and we never locked ANYTHING. Not doors, not cars, slept with our windows open in the summer, left our windows open when we went out on nice days (rare, haha)-they think I am just getting old and remembering things better than they really were.
These kids and their kids--they'll go straight into Brazil/South Africa and never know it doesn't have to be this way.
In the 60’s we lived in the country not far from a prison farm. We always left our keys in the car so if there was an escaped convict they would take the car and not come in the house looking for the key.
