I make the assumption that a principal's allowance is not an allowance, but a payment for doing a bigger job. We then end up with something that is consistent with what we saw in the Defence Forces. Am I right in saying that once the principal's allowance is stripped out, as one goes up the income scale the percentage of one's total income that consists of allowances decreases?
