Comparing the UK to the USSR, steg? Wow, keep it up ... you (like many "Yes" supporters) are doing such a good job of managing the goodwill of your ex-compatriots that you're going to need if you are (in the words of the OP) to benefit after going it "alone".
I'm joking, of course. This is why I believe that Scotland can't benefit:
I can't see a Yes vote happening without the UK being denigrated even more than it already has been by Yes supporters. Should a Yes vote happen, I can't see any way that Scotland can benefit, and the rest of the UK not suffer (e.g. the sheer expense of "transition"; not to mention, today, the currency dropping and share prices dropping in Scottish institutions in which UK shareholders and pensioners have a stake). And, if the rest of the UK does suffer, I can't see it providing Scotland the support that Scotland will need in order to continue to benefit - which all makes the idea of Scotland benefiting a contradiction.
