Let's take a married household earning about $45,000, with three dependents, owns a home, and gives slightly more than average to charity (as Republicans are wont to do).
For tax year 2007 this household would pay $0 in federal income tax. In fact, not only would they pay $0, but they would get over $2400 from the federal government. This is not money being refunded to them - it's free money from the government.
Now, if this same household had filed using 1999's tax laws, they would have owed $950. That's a $3,300 swing in the wrong direction.
So, over the next year or so as the Bush tax cuts are debated, the phrases, "tax cuts for the rich" or "tax cuts for the wealthiest 1%" or any derivation thereof, are hereby banned.
