I certainly can't see any reason why any literate person should have to pay a fee for a 1040EZ. Why should anyone go to all of the effort to become a CPA or EA and spend their time doing 1040EZ returns. It is like a person becoming a lawyer and doing nothing but notarize documents when almost anyone can become a notary without even a high school education being required.
A tax professional should be someone who normally handles situations beyond just a basic, simple return. Of course, there are some people who might be reluctant to prepare even a 1040EZ and want help, but they should be few and far between. The only such returns I ever do are those of the children of clients.
On the other hand, I've known some accountants who couldn't prepare their own return. Once I had a tax client who was an FDIC auditor.
