The IRS might need a bigger budget to make them morally pay. Prosecution is expensive.
I’m entirely in support, of course, so I say we should increase the IRS’s budget and do it. But I also get why the IRS doesn’t want to walk up to Congress right now, hat in hand, and say “We spent more money prosecuting them than we gained” or anything close to that, and give the GOP ammo for defunding them again.
