They go with a White House office to examine the fence.
The Bangladesh contractor takes out a tape measure and does some measuring, then works some figures with a pencil. "Well", he says, "I figure the job will run about $900. ($400 for materials, $400 for my team and $100 profit for me)".
The Chinese contractor also does some measuring and figuring, then says, "I can do this job for $700. ($300 for materials, $300 for my team and $100 profit for me)".
The Indian contractor doesn't measure or figure, but leans over to the White House official and whispers, "$2,700."
The official, outraged says, "You didn't even measure like the other guys! How did you come up with such a high figure?" The Indian contractor whispers back,
"$1000 for me, $1000 for you, and we hire the guy from China to fix the fence."
"Done!" replies the government official.
