It takes two full time salaries just for 2 people to afford the basics, not including a house. You want them to go on one salary and add kids to that? Doesnt work. They dont want to live like that when theres money out there to be made so they can have a better life. Something has to give and in many instances its having kids.This is another reason that we are in slow decline. Women, particularly white women were convinced to not have children, and their careers are so important. In reality, for most the careers are not. When they pass on, there will be little written on their tombstones and few at their funerals.
