So let's say $4 a day; $24 a week (six-day work week); 51 weeks (assuming they get one week vacation time) is $1224 a year gross. If a group of ten worker produced 25 arfs a day that's $1.60 per plane, and say, maybe $25 in materials per plane gives you $26.60 for a product that sells in the US for $250 or more. Someone's getting very rich. Well, I now have one more reason to build.
