In How Much Are Public School Teachers Paid the Manhattan Institute author used hourly earnings data to contend that teachers are better paid than most white-collar professionals. This might have been impressive except, as our reviewer noted "this approach is fundamentally flawed because the [dataset’s] calculation of weeks and hours worked is very different for teachers and other professionals. In fact, the Bureau of Labor Statistics – which publishes the [dataset] – has explicitly warned its users not to use hourly rates of pay in this exact same context."
