I'm not. No there isn't a wage gap when you control for factors that affect wages.

For example, men are more inclined to negotiate for a higher salary or ask for raises. Women tend to take career paths into jobs that don't pay as much. On equivalent jobs with similar resumes that wage gap disappears.

Of course having a kid and deciding to stay home/take time off to care for them have consequences in the short and long term. That's a year or more off the experience you have as an employee.

I wouldn't recommend using the USA Today as any sort of legitimate source on anything. Try something like The Department of Labour instead; http://www.the-spearhead.com/2010/03/08/department-of-labor-gender-wage-gap-a-myth/
