Accounting for the Big Fish . . .
If corporations are people, corporations have an ethical obligation to make sure that they comply with Federal Income Tax Laws. Not only is it unethical to store money offshore, to avoid paying income tax on it and to pay the executives outlandish salaries, also is it unethical for companies to spend money lobbying to control the tax laws that were originally created to PROTECT the most vulnerable.
The Founding Fathers of the Constitution of the United States of America foresaw and understood the problems that occur when powerful interests run rampant, creating monopolies. Federal Income Tax is a "shield" that, at the very least, slows down the creation of monopoly powers, and protects citizens from entities (whether PERSON or CORPORATE) that seek to control prices.

The above pages are from a book published in 1895; $4000 adjusted for inflation today is approximately equal to $100,000. You read correctly: If the Federal Income Tax Law as it was originally intended were implemented today, nobody earning under $100,000 would have to pay ANY Income Tax at all -- not a dime.
The $4000 (1895) / $100,000 (2011) "limit" may seem random, but it's actually very smart because it encourages corporations to raise wages and salaries of employees as a means to minimize tax payments to the government. Assuming a businessman making over $100K GENUINELY wants "small government," he would choose to raise the wages and salaries of his employees before giving himself a "raise" that would, by default, be giving a larger share to the government.
The "graduated" Income Tax rate actually makes a lot of sense; it doesn't so much punish greed as it does encourage benevolence. To those who have been given much, much is expected . . .
