Sure - suspicious is one thing ... paranoid is another. You should invest a small amount of time in both reading the bill and the economic material on the FairTax website.
The bill:

I understand your fears about what Congress "might" do with the Fair Tax. But you've got to understand, they ARE doing cr*p to us right now with the current law. Have you ever heard a politician gleefully announce "We've taken x million people completely off the income tax rolls"? Well, what that means is now x million more people have no vested interest whatsoever in how much their government cost. And now they will vote for whoever will keep them that way. And guess who pays for it? US!
