I have spent my life living in places where the culture is foreign. Years living in strange cultures. Building landscapes and gardens with people from other cultures. So I have become an observer of signs that focus on cultural differences. Please see the image below. Then try to draw your own conclusion.
Working on landscaping projects, I have often found that labourers employed by contractors receive a very low salary. Sometimes those labourers have not entered the country legally. Sometimes they have never yet encountered cars or trucks. Believe it or not. People of the earth.
