I agree. If you have more than one child, one parent's salary will go directly and entirely to pay for child care. It's also likely that one parent will need to work fewer hours and be available to drop off / pick up / emergency pick up the kids at day care -- which means at least one parent will need to be partially not working or at least not advancing in his/her career.

However, raising kids is very difficult and emotionally draining. Personally, I feel parental involvement is much more important than whatever might have been called a middle class lifestyle.
