I once worked for a multimillionaire who got audited. He did have to sell a bunch of properties, cars and other toys, to pay taxes, interest, and fines, and got ten years in the pen. This was in the nineties, and he was well-liked, but I never* heard, nor heard of, anyone claim it was unfair, including those who benefited from his corruption, except one guy who bought and sold particular high-end products for him who was also audited, and avoided prison, but idk whether he had to pay delinquent taxes, penalties and interest or not.
