This is why most modern governments have a system of progressive taxation, which, just so we know we're talking about the same thing, means that the more you make, the higher your income tax rate becomes. In the US, you're taxed only 10% on your first $8,000 or so if you're filing as single (although deductions and credits often reduce this amount further), and then your next $25,000 or so is taxed at 15%, and the rate continues to increase on increasing amounts of income. (See also this.)
Such a system of taxation has been endorsed by that notorious commie Adam Smith: "It is not very unreasonable that the rich should contribute to the public expence, not only in proportion to their revenue, but something more than in that proportion."
To restate the first paragraph in a different way, an additional 1/9 of your income goes much farther when you're making very little than when you're making very much. I hope this explains why there is no crack and no cognitive dissonance required to say that the difference between an income of $90 and $100 is much more significant than the difference between incomes of $9,000 and $10,000.
People are different because they exist independently of laws.
You may point out that corporations are comprised, principally, of groups of people, and you'd be right, but they have more power than do individuals, primarily because they have more money than any person could hope to amass. When you combine this greater power with limited liability and other special rights that are allowed them, it becomes quite obvious that it is entirely appropriate to restrict their behavior.
I'm not arguing that they are sensible units of measure, just that they are actual units of measure.
