Some more thoughts on economic and general "modeling" (socio-economic, etc) in view of current trends and dynamics:
a) Do countries in our era need to be large enough to have a sufficient internal market for economic sovereignty?
"Large" enough in terms of what?
b) Is it prudent for a developed + Services based economy to rely too much
1) on the Financial Services sector of econ activity? (is the UK one of them)?
2) On exports (eg Germany, South Korea, Taiwan, China, etc)?
