There are lots of clever Economists who expalin how different choices will cost / bring in millions or billions but I have yet to see anything promising more than 2k per citizen - and to be honest I doubt anyone will move house to get a 2k pay raise, so the overall effect - minimal
of course some areas of Scotland are long term grindingly poor and recieive lots of start up credits (they are called enterprise zones) - but they are nit focused on HN style startups, services and light industry is the bigger recipien of enterprise grants.
