And David Cameron would have been more effective at convincing British voters the EU is worth keeping.
The goal now is to minimise anything that makes Europe a less attractive place to do business. This should be achievable.
An investor looking at the UK today sees a broad-based, rich and open economy with leadership in several important sectors, a competitive currency and a skilled and flexible workforce.
However, they also see political turmoil feeding through into economic uncertainty.
That is the problem — and the opportunity. It is possible to imagine a scenario whereby the UK suffers a consumer-led recession that impacts huge swathes of the economy from real estate to retail.
It is also possible to picture a scenario where the UK economy slows for a few quarters then resumes its growth, spurred by a weaker pound and an accommodation with the EU that allows trade to continue largely unfettered.
This latter scenario is the most rational for all parties to work towards. The UK will need to realise that a more competitive currency is not enough to support what is predominantly a services economy.
And the EU will need to realise that its own economic growth needs a stronger Britain, not a weaker one.
In the meantime, political posturing will surely send some chills down the spines of markets, and will encourage central banks to reaffirm their support.
Therefore, as a global investor, we are positioned for months of volatility by having very balanced portfolios.
That said, we have increased our exposure to equity markets across the globe.
