Reply #21: No, because the payroll tax cuts off at a little over $100k.

So in other words, someone making $500,000 a year gets the same "payroll tax cut" as someone making $100,000, but someone making $50,000 gets a much higher percentage of their income back than does the person making $500,000.

Not to mention, "flat taxes" are inherently regressive in nature, because the people with the least amount of money have the least discretionary funds. Once you subtract basic living expenses, you're taking a much larger chunk of someone's available income if they make a little money than if they make a lot of money.
