Myrdal was highly critical of developments in the operation of preschools for children in Sweden. Consequently, she published the book "Urban Children" (1935), where she presented her ideas for a newly reformed Swedish preschool system. She argued that contemporary child care was flawed. The system was polarized between two extremes – measures of 'poor relief' for the less well-off contrasted with those measures which prepared children from wealthier families for private schools. She stressed that there were material obstacles in the way of being able to access a good education. Therefore, social and economic reforms were needed. Myrdal wanted to combine and integrate the two extremes.
