Objections and Replies

Notes

{Ethics} Strong ethical considerations may dominate financial concerns. But to invoke ethics when speaking about money might be seen as deflection. Best to parry the objection directly, *then* top it with ethical considerations.

{Reinsurance} Check how reinsurers, insurers, and actuaries look at this matter. You should see discussions that tend to be grounded in reality.

{Military} Invoking military spending usually shuts off concerns about the cost of social programs.
