Kids as status symbols

Here's some odd news, given what we're told about wealth and having children. It seems that the inverse relationship between wealth and having kids stops and reverses itself at higher income levels. I guess whenever you can start to afford to have one of the spouses stay home you can afford to have more kids. I wonder what that means for this point about the dependency ratio. I suppose it only becomes more of a "problem" if we get out of this funk economically. Besides, the inverse relationship between income and children only seems to reverse itself at higher income levels, say above $250,000.
