United financial kingdom
It used to be that business leaders in Scotland kept away from any controversy around the country's constitutional future.
A few lined up on either side of the debate ahead of the 2007 election, when endorsements dominated the final 10 days.
But since then, almost all have been very careful to avoid comment on the prospect of a referendum and how business would view a move towards independence.
But there's a bold opinion been expressed by Scottish Financial Enterprise, the trade body representing the banks, asset managers and insurers.
In written evidence to the Holyrood committee newly embarked on an inquiry into the finance sector, SFE makes it clear where it stands.
In answer to the question: how should Scotland differentiate itself and promote itself in future, the submission reads: "We need to take the initiative and, to do that, continued co-ordination between Scottish and UK agencies and actors is essential. Scotland's position as part of the UK and part of the City of London brand is very important internationally."
It goes on: "More than half of financial services jobs in the UK are outside London and the distinctive nature and heritage of Scotland as a financial centre enhances and broadens the UK's promotional pitch for international business."
There follow a couple of calls for the Scottish Government to avoid actions that damage business's prospects in international markets, particularly in relation to other parts of the UK.
It doesn't actually spell out the possibility of higher income tax, but you can see where they're going with this: "We suggest that all policy proposals at the hand of the Scottish Government should be subject to an 'international competitiveness assessment', similar to environmental impact assessments. If a policy seems likely to harm our international competitiveness, consideration of that should weigh heavily in any decision whether to proceed."
The warning is of a high speed rail network that stops in northern England. That is seen as the most significant infrastructure issue in the immediate future, "and we cannot afford to put Scotland at a disadvantage to competitor areas south of the border by allowing High Speed Rail links to stop short of Scotland".
