The Biggest Housing Program Isn't for the Poor

In 1913 the first Form 1040 let people deduct all the interest they paid, on a farm, a store or a house, without a word about housing. After 2017 about 20 million fewer returns claimed the mortgage interest deduction, and the video asks why the biggest tax break for homeowners was never that line at all. This page lists every source behind the video's claims and credits every piece of footage, image, sound and music in it.
