If you look at the manufacturers, who have purposely driven costs up in the drive of success, and I think thats the primary factor in the current economic situation of F1. So I think we pretty much agree on 95% of what has been said, but main difference may be the primary cause of cost increases, whilst I understand (from what you've said) you believe its the rule changes at fault for high costs of F1, I think its the manufacturers 'invest at all costs' philosophy they have adapted.
