I speak 3 languages fluently (english, french, german) plus my native language. You probably only understand english. If the T D mistake is the only one you can find it shows how miserable you are. If people have no real arguments they try to find words that were written wrong. Poor man. Your profile is probably: arrogant american who thinks he is the only one with the undisputed truth, obese, low education, and no job or flipping burgers, an probably paying almost no taxes. If you speak about taxing revenues it is clear you have no clue about economics or accountancy (this confirms your profile). Expenses made to generate this revenues are deductible which is logical. If you pay taxes on revenues you pay taxes on the salaries you pay to employees, you pay taxes on electricity you use... So in your opinion Buffet should pay taxes on the salary he paid to Bosanek. You don't even know the economical definition of the word "revenues".
