The most coherent of the young people I spoke to understood the macro-economic risk. But they weighed it against two increasingly intolerable burdens: the inability of Scotland's relatively left-leaning electorate to influence Westminster; and the inability to budge Scottish Labour away from the free-market and pro-austerity policies associated with Brown and Darling.
What this means is, even if the yes vote fails on 18 September, scoring somewhere in the mid 40s, the pattern of all future Scottish independence debates is set.
Independence has become a narrative of the people against big government; about an energised Scottish street, bar and nightclub versus the sleazy elite of official politics.
Having spent last week in Glasgow, I would say the biggest variable is going to be turnout. When political enthusiasm reaches the relatively apolitical world of the council estate, the pub, the nightclub and energises people, turnout can do weird things to poll predictions. Alex Salmondclaimed there would be 80% turnout. I think the chances are even higher – and if the polls actually cope with such volume, every percentage point above normal introduces volatility not captured by normal polling.
At the Sub Club, a world-famous nightspot in Glasgow, the debate was remarkably coherent, even at 2am among the intoxicated smokers huddled outside. If I could distil the vox pops among those under-30s to a single thought it would be: "We want to run our own country."
