The theme of Monkey Beach

I believe this book is talking about how many Native Canadians have gone downhill since the Europeans arrived. In the news, we only hear about the Natives that murdered, raped, and all the drunks and drug addicts. I believe there is more, in this book it shows many families and people who have problems, but it also shows that there are families who are fine, and are not out committing crimes. For example, Lisa's family.
