Funny, I think she has conveniently recast "the problem" as whether to replace the commercial tax filing industry with something that might be free to the taxpayer. Because yes they doing just fine, thank you, paying us for that convenience, so there is no problem if you look at it that way.
But if the problem is helping people file their taxes easier, then clearly Intuit didn't think that that was a solution in search of a problem, for them to build a whole industry around it...
Funny how entrenched interests will go to great lengths to redefine and recast what the fundamental goal of the government should be. And usually that recasting is some kind of distraction away from the question whether the government should serve the people, or serve specific entrenched interests.
