But "income tax" is a misleading name for this. It's a tax on corporate profits. The letter wants you to compare this rate to _your_ rate of income tax and be shocked. But this is stupid, the corporation is not a human being. For those profits to be enjoyed by anyone, they have to be paid out again as salary, or dividend, or recovered by selling shares... and these transactions are all taxed. And, of course, all of this money which is now profit was taxed when whoever bought the computer was charged VAT. (Who signs the check to the tax man on each of these transactions is irrelevant, but another common way to mislead people for outrage. The tax man stands between you and Apple and demands VAT... and between Apple and their employee and demands income tax... how this is collected is, again, an implementation detail.)
