Chelsy, the population of the 1840's was decimated by famine caused by British economic policy. We were producing masses of food; wheat, meat, eggs etc... which was shipped out by the British government to sell to those who could pay a much higher price. Potatoes made up the bulk of the poors diet and they starved because they couldn't afford to buy food and pay their rents to the British landlords when the crops failed. The population reduced from over 9 million pre famine to under three million at the turn of 1900, that figure includes Northern Ireland. Nothing to do with independence, everything to do with being run by a foreign political class that oppressed and despised them. The entire island North and South has a population of about 5 and a half million combined now.
Astounding that some people here think that the Poles, Lithuanians, Latvians and the rest are desperate to get back under soviet dictatorship because they were so much better. They're much better off now as poor as they may seem compared to the west. There are all sorts of minorities and I'm sure a tiny few in those countries may long for the days of being dictated to, persecuted and starved to death from politicians thousands of miles away but I've yet to meet any and apart from a Russian minority in Eastern Ukraine who wish to return to people most like them, there is no majority will to return to Moscow. That's the majorities greatest fear because they remember the horror of it and the powerlessness to change anything.
It's up to the Scots to make their own choices. They can rule themselves for better or worse or they can choose to continue to be ruled by business interests from London. They can choose to determine their own foreign policy or continue to be dragged into resource wars they don't believe in. They can choose to take the power allowing them to do what's necessary to benefit their local environment or be dictated to by people who've never been there and don't care for the consequences of bad policies.
If some businesses move out, more will move in and be created if the government has the sense to offer a slightly lower corporate tax rate than Britain. They will have the power to do whatever they want to the benefit of themselves. It could be a wonderful opportunity for them to recharge their country.
Nobody needs Westminster, they're a boil on the arse of the world and Scotland would be well rid of them.
