So we have tax laws that rob our country it's due to cushion the blow to rich men's failed business endeavors?
The fuck is that shit.
It's a completely normal thing that everyone does. Just as you get taxed for income, you can claim losses against your income.
If you're a US taxpayer, when you're filling out your taxes, this is what the "standard deduction" is: an assumed "typical" reduction from your taxable income that everyone is allowed to claim if they don't want to carefully itemize all losses.
But when people have had really big losses, they can itemize losses rather than claim the standard deduction and thus count the huge losses against income to get a bigger deduction. If the loss is so big that it totally eliminates your income tax, you're allowed to carry it forward and apply it to the next year, and so on.
