> Capitalist societies are one of the few places where children don't work.

This is simply not true. Essentially every capitalist country has had extensive child labor for long periods in their capitalist development. There was widespread child labor in the early 1900s U.S. - a very capitalist economy then and now. Many developing countries with capitalist economies (such as Ivory Coast and Ghana - you know, the ones in the article) also have extensive child labor today.
