Corporate crime is resurgent.

And yet we rarely hear from our most insightful corporate critics.

There are scores of them.

They are well read, well spoken, insightful, write books, have track records.

But if you listen to public radio and television, they rarely appear.

We did a snap survey of five public radio and television shows over the last five years.

The five shows — The Diane Rehm Show, Fresh Air with Terry Gross, On Point with Tom Ashbrook, The Charlie Rose Show and The NewsHour on PBS.

The five corporate critics: Noam Chomsky, Barbara Ehrenreich, Chris Hedges, Jim Hightower and Ralph Nader.

Over the past five years on the five shows, Chomsky appeared once (On Point), Ehrenreich appeared twice (Charlie Rose, On Point), Hedges appeared once (On Point), Hightower appeared once (On Point), and Nader appeared once (NewsHour).

By contrast, over the last five years, New York Times columnist and corporatist Tom Friedman appeared roughly 15 times on just the Charlie Rose Show.

Now, you might look and this and say — you are so 1992.

Public radio was taken over by the corporations 20 years ago — maybe more.

And now you’re telling us?

To what end?

Well, just because we have put up with it for 20 years doesn’t mean we having to keep putting up with it.

Rehm, Gross, Ashbrook, Rose and Gwen Ifill should be shamed into submission.

Instead of calling in to the Diane Rehm Show and saying, as many callers do — “Great show Diane,” call in and say — “Diane, have you no shame?”

“In five years you haven’t had on Noam Chomsky, Barbara Ehrenreich, Chris Hedges, Jim Hightower or Ralph Nader? Why not?”

It’s time we wean them off the corporate machine.

And put the public back in public radio and television.
