1) Think and act global
2) View England as a market, not a rich uncle
3) Embrace and manage risk
4) Organise to enable everybody to add value
5) Make a bigger pie rather than conspire to get a bigger slice through privilege
The barriers are a)dependency culture -b)dominance of the public sector c) tribal politics
and you can add:
1. Government focussed on Wealth creation for Scotland versus current Social engineering
2. Education system that meets the demands of industry (in whatever form that 'industry' may be - manufacturing or service)
3. Transport system that allows people to move more freely in and out of Scotland to trade especially with Europe and the US
The additional barrier is quality of leadership. As you rightly identify the necessity to move beyond tribal politics is paramount to making a difference
