Like all of these "Very short introduction" books it does what it says - provides a kind of thumbnail intro to what are actually very big topics.

As far as content, you're just as well off going to the "Capitalism" page of Wikipedia and just clicking around for a week. But the book does provide a good historical and geographic structure to the evolution of different capitalism(s), so in that respect it's kind of a perfect intro, and could spark some great conversations.

Actually if you've never read on the origins and alternatives to capitalism, this book might just blow your mind. Maybe a good book for the teenager, or dad, in your life who thinks they know everything already.
