I'm not an SNP supporter although I voted for Scottish independence in the referendum. One of the reasons was I thought it was our best chance of remaining in the EU.
I hope Scotland don't leave, I don't believe they are currently in a sufficiently good financial position to leave and there is no guarantee of them quickly joining the EU, it could take several years.
Although the Scottish economy isn't great it doesn't require the regional development funding that Wales & Cornwall do. For those of us who can remember, the UK's economy wasn't that great when we joined the EEC back in the 1970s. Fed Reserve had intervened & eventually we were bailed out by the IMF. With the right infrastructure there is plenty of scope for Scotland to develop it's economy & there is interest from City firms to relocate to Scotland to secure single market status.

EU accession conditions are set out in the Copenhagen Agreement.
The economic criteria is the existence of a functioning market economy as well as the capacity to cope with competitive pressures and market forces within the EU. Scotland can meet this.
Forbes article is a bit misleading when it says in order to join the EU you’ve got to have a budget deficit of 3% of GDP or less. A budget deficit of 3% of GDP or less is the condition for joining the Eurozone not the EU.
Having said that if Scotland were to hold indyref2 & become independent before the UK leaves the EU it may be possible to remain in the EU by treaty amendment rather can through the accession process.
