No, it's not that I (and you) are pure and others are evil. It's that I (and you) would save pennies at best. The people that have the 82% of the wealth would save enough by gaming the system to make it worthwhile.
You (and I) are just not rich enough for tax shenanigans to be worth it. You've got to be half a billion dollars worth of tax shenanigans (like trump's family) rich to make it worth trying to play the game. So no, I'm not surprised that your husband didn't bother saving the few sheckels he might have saved with claiming the home office. Little people like you and me have to jump through too many hoops to make such a small deduction worthwhile. But for someone at the Walton or Koch level of wealth, playing those games actually makes a noticeable difference.
