What I find ridiculous is that not one of these workers seem to wonder where their efforts are going into. When I was younger, I participated at some kingdom/convention hall constructions. Frankly, I don't regret the work I did: These places had nothing. So if you support a cause, what ever that is, that makes sense. What is absolute absurdity is to use the same FREE labor in areas who can sell a previous property to buy a new one, cash! Even when I was fully "in", I don't believe I would have ever done such a thing. Oh, and to make matters even more insulting, within the first month in that fully paid hall, they will explain how everyone should still contribute financially to the hall like everyone else in the country, you know, making them feel like they owe the money to some bank!
Here is a thought: If I ever ended up helping with such a project, I would charge 30$ per hour. So, lets say I had worked a long weekend (3 days) that would be 24 hours (720$). Knowing that my regular monthly contribution would be 10$ per month, this means I would not give a dim to the contribution box for the next 6 years! Perhaps some of these volunteers have that logic... who knows.
