The True Cost of Motherhood -- according to Yahoo! and Financially Fit

I just read an interesting article on the True Cost of Motherhood.

Basically, it was about how much having a child affects a woman's finances.

Here are their findings:

• Low-skilled women don’t get very big raises, and having kids does little to change that.The so-called wage trajectories (think of a line graph showing a worker’s wages growing over time) of low-skilled women are much flatter than those of high-skilled women. Having children didn’t change those trajectories very much.
• For high-skilled women, kids spell the end of raises. High-skilled women have steep wage trajectories. Those trajectories flatten out almost precisely at the moment they have children.
• Low-skilled women don’t seem to make their lost wages back. Ten years after having children, low-skilled women have wages that are six percent lower than their counterparts.
• High-skilled women don’t make that money back, either. Ten years after having children, high-skilled women have wages that are 24 percent lower than their counterparts.
• Becoming a parent seems to have no effect on men’s wages.
  

And my response?

DUH.

Really? We needed to do a study on something that has been common knowledge for 30 years, at least?

But that wasn't the part that made me really mad... it was the comments.
