This is normal - the rich don't pay tax.
The normal thing here is someone on Slashdot didnt read the TFA. The debate is about corporate taxation not "the rich". The individuals still pay the tax on wages.
It is fair (intellectually, not necissarily a correct posititon) to argue that income should be taxed twice, once at the corporation an once with the investor / employee. It is also fair (intellectually, not necissarily a correct posititon) to debate deductions. But it is knee jerk illogic to confuse a debate about corporate taxation with the debate whether "the rich" pay their fair share.
