I don't think you are, in all likelihood. Things do cost more than we sometimes anticipate. We sometimes make demands that have not been fully costed out, and when people go to execute those demands they unfortunately prove to be more costly.
But I come back to the fundamental issue that without understanding how the resources are being spent today, and on what, it's a very difficult discussion to have, because we are starting in a somewhat dark place.
It's not unlike the way a parent conducts a discussion with a teenager. You give a kid $20 and he goes out for the evening. He comes back and asks for another $20, and you ask what happened to the first $20. If there's not some kind of accounting, even in that minimalist sense, it's not very encouraging to just keep throwing more money at it.
We need to figure out what the money is currently being spent on, and then make the right assessment, if additional resources are required, to what end.
