My experience of economics modelling (admittedly very limited) is that it can't help but be skewed towards the status quo. The only solid figures they can use are historical, which will only act as an anchor to the predictions of the potential future.

Additionally, economic modelling is often used as a risk analysis tool, and 'knowns' (with solid historical numbers and patterns) are always less risky than 'unknowns' with limited information.

'New' always faces an uphill battle on many fronts.
