Before the huge development of Whitehorse Village into Wuxi New Town, the residents used to earn very little - around 200 pounds a year - so they couldn't BUILD wealth, it was just enough to live off. The only way many people could make this money was farming. Even so, many husbands left as migrant workers to the cities to send money home, leaving the wife at home to look after the children and farm. Often the children help the mother to farm, but obviously sometimes the labour is too hard for children, so the grandparents babysit or help around the house. When the huge change happened, the mothers and the fathers were able to work and earn a lot more money for the family, meaning less manual labour was required and the mothers could live less stressful lives.
