No, I believe it’s a statement of fact. Another statement of fact is that most cultures do not see bribes as corruption (I believe they are, but I’m referring to how other cultures view them). They believe it is perfectly acceptable for you to have to bribe an official to get permits and the like through the system.
These things should have been explained to the couple before they headed over there.
Many of the Missionaries I know refer to bribes as “unexpected taxes”, since a tax it is.
I believe their complaint was that the bribes served to official overlook UNSAFE BUILDING PRACTICES!!
Much different than simple greasing the skids!
