My take on Peer Gynt - Peer is exiled by his community and seeks to be excepted into another yet still can not with stand the strength of his personality and imagination. The lack of emotional and physical support that's gained in a community, is lost to Peer as well as his egotistic attitude is a bad combination. causing him to retreat into his imagination and lyes. This forced rejection from a community also happens to other character in the play, for example the Dover-Master.
Viewing Peer like this lead me to look at the history and controversy surrounding poor built council housing, and the communities that live within them. Bad planning, has created a massive wastage money, resources and materials. Yet they have always have retained a strong sense of community. But because of this poor planning, these building have to be knocked down at great expense and the people living in them have to be relocated to building sights outside the city where they become ousted from the communities (the trolls) leaving friends and families and having no trust in the government. Because of this, new groups of people are forces to make new communities which they want to keep isolated from any one els (so they don't have to relay on other people).
