With regards to the Westerlands:
The Output from the Gold Mines (The Lanaster's mines at least) was drastically decreasing, and thus there must be more and more unemployment. Due to the war of the Five Kings there would be a smaller population, and thus the issues of unemployment would be lessened, however, in a situation the war did not happen or once it ends, unemployment will plague the westerlands for some time.
Where did you get that? Unless you are referencing the show? Which the World book, and GRRM himself, has specifically said is show only-the mines are still going strong.
