The folks that build the buildings

We saw some folks on the back of a pickup the other day - they were on the way to work at a nearby construction site.  In less than a month, those folks have built 15 or 20 floors of a high rise across the street, working most of the day and night.  Almost exactly how it works in the US, except perhaps the ethnicity of the construction workers.

Take a good look - these are the folks that build much of the world you live in.
