„In the case of older preschoolers, preschool participation has the potential to be beneficial for development and to produce lasting effects for children from disadvantaged families. It is not clear why advantaged children often seem not to benefit from universal childcare. One reason may be that universal childcare teaches skills that children from more advantaged backgrounds would learn at home anyway.“
