Economist: If the economy grows stronger, employment will increase, and hence more parents will need to find day care for their young children  Unfortunately, in a stronger economy many day-care workers will quit to take better-paying jobs in other fields

If the economy grows stronger, the number of new day-care workers will not be significantly greater than the number of day-care workers who move to better-paying jobs in other fields.
