What is the author's tone in No Logo: Taking Aim at the Brand Bullies by Naomi Klein?

Klein's tone is both combative and redemptive. From her loft apartment in Toronto, she looks out upon the old garment district of the city, once teeming with immigrants who worked daily, in the production of clothing that was then sold by small independent retailers. Like most former industrial cities, the factories are closed and have been converted to lofts, restaurants, and clubs, remaking the areas into chic neighborhoods where affluent citizens can live, shop and play.
