The writer was not against capitalism, but against capitalism in its current form. He basically speaks about many areas where capitalism has gone wrong. Examples include forcing free trade in African countries, policies to make the rich richer with the hope that the rest of us will also become rich etc.
Overall, it was an interesting read. He certainly makes some important points though I don't agree with everything he says. For example, he says that sometimes regulations makes it easier for companies to make good decisions. This might be true, but I disagree with the amount of it he proposes.
