Salaries are not exorbitant. Given that this is a global audience, and that even within the US the salary disparity across regions and industries is tremendous, could you be more specific than "not exorbitant"? My guess, from having a parent who taught at a likely even lower paying institution in rural Wisconsin, is that real numbers would make your case better than a euphemism to which people will attach their own expectations.
