I watched 98% of the video and really I dont see this as a huge issue, yes it is wrong for the channels to claim in their description that the constructions are done by hand and with less people but given how transparent the cameraman is about all of these things and that they confirm private land is leased for the purposes of filming. But, I can also see the perspective of some builders in SE Asia coming up with a way to make much more money from doing work they already have the skills to do by filming it and that I think I could forgive the fibbing if they just acknowledged how the builds were done, some of them are pretty awesome even if they aren't hand-dug.
