Would an independent Scotland run the risk of becoming a rentier (petro-) state? I've read that much of the dialogue about the upcoming referendum has to do with Scotland's oil reserves (which are dwindling). Would an independent Scottish economy run the risk of becoming over-dependent on its fossil fuel sector (like Venezuela, or to a lesser extent Russia), or does it have other strong sectors (e.g. manufacturing, finance) that look to remain stable into the future but are simply less-discussed?
