The IRS loves to pick on people too poor to defend themselves.
They will frequently break the law and keep your money or deny a deduction just to see if you will go to court to fight them.
And congress is perfectly happy to see you repressed by these thugs.
In a just world, the people who work at the IRS wouldn't be government employees (because there would be NO IRS). They'd be employed picking green beans by hand in the hot sun day after day. And most congressmen would be behind bars.
