I would be interested to see a comparison of people using TurboTax v. the IRS software. With TurboTax you pay a B.S premium up front, but at least you know they have some incentive to find refunds for you as much as is possible
To the extent IRS leadership has political incentives, it's in making it easier for ordinary Americans to get a refund.

I suspect that the IRS will never have the kind of support to go seeking out deductions. They're probably happy to leave that to Intuit.
