Which route is more effective? Decentralisation of authority, giving more power to individual regions or having most of the affairs of a nation decided by a central authority?
Personally I favour a more localist viewpoint, I feel like centralisation of a country makes things inefficient and out of touch, and the people of that nation cannot stay connected without some extreme show of Nationalism, i.e - Americans and how they rally around the stars and stripes. You can see the same theme within all major nations that span a large portion of land and encompass diverse peoples. Most notable are Canada, The United States and the old USSR.
Ask anyone in Western Canada or the Eastern Maritime Provinces if Ottawa really relates to them and if they represent their interests. You can take every single provincial border and find 2 very different types of people on either side of that line. There are separatist movements all over Canada, from the western Cascadian Republic, to the Quèbec Separatists.
The United States has been able to hold together their nationality through a common flag and a common purpose. Nationalism that borders on the extreme keeps that nation in check, but there are still sessation movements like the Pacific Northwest and most notably that I learned about on this forum, the Native-American Lakota Nation that popped up right dead-centre of the USA.
Soviet Russia was such a tightly centralised system of governance that it couldnt possibly have been in touch with its satalite nations. Damn near every single nation that comprised the USSR had some sort of opposition to its control and lack of ethnic freedoms.
All in all, decentralising the authority base of a government and giving more power and scope to Provincial, State, Territorial governments, and allowing them to operate almost like little nations within a nation will generate a better way of governance. It would boost voter turn outs, make elections more pertaining to the people who are voting, and issue can get hammered out faster and more efficiently.
