Fleece those American marks.

I think using the terms "fleece" and "marks" is overly strong to describe what's going on here. This is much more like reality television, which isn't just documenting the natural goings on but is produced and semi-scripted. These videos are for entertainment and the peeps in South East Asia found a way to earn some money from the "Internet Revolution". (This all assumes there isn't some exploitation scheme going on between the video producers and the laborers/builders!)
