2. Price Gouging- It is unethical to raise prices on a product far above what is necessary just because you can. Remember Martin Shkreli who raised the price on the life saving pill Daraprim from $13.50 to $750 just because it wasn’t illegal? Just because he could?
The second temptation that raises its head toward the middle of the finance raising effort is to claim that the set up cost or the monthly cost of living on the field is astronomically higher than what it really is.
At the end of the day you have to live with your conscience and your supporters need to have confidence in your judgement. For my part, I don’t want to meet everyone’s lowest standard of living or I would be living in a fixer-upper forever. At the same time I have to guard against the temptation to raise my living standards to a level higher than what is appropriate. This is a subjective standard that every man must seek God on and live according to what will best advance the gospel.
