Parents Leave Raising Their Chidren to Others

The article Love you and leave you describes how parents in China are leaving their children to work in the city see article and quote below:

"Under Mao Zedong, countless families were ripped apart. Mao sent millions of parents into labour camps and their children to the countryside; he forced families to abandon the stoves in their homes and to use communal kitchens and dorms. Even so, Mao failed, ultimately, to destroy the family as the basic cell of Chinese society."

"Today, what the dictator was unable to accomplish with force is being realised instead by the lure of money. It is 33 years since the Communist party embarked on a course of economic reform, under “paramount leader” Deng Xiaoping, and increasing numbers of Chinese are choosing to live permanently separated from their children as they search for a better life." see http://www.ft.com/cms/s/2/42417c1a-2f34-11e0-88ec-00144feabdc0.html#ixzz1HLLeYtNI

Is this happening worldwide, only in places like North America more children still live with at least one of their parents?  Comment on this post to start a dialogue.
