However, this will only occur if they took losses, so it is really a discount of ~35% on negative income. This would also apply to someone who is not rich, i.e. a software dev sole proprietor who cashed out big losses in March in the stock market and then applied those losses against their normal income to end up reporting 64k in income instead of 100k (normally 36k in losses would have to be stretched over 12 years of tax returns).
I understand this doesn't fit the narrative, but please comment if it is incorrect instead of downvoting.
