What we're seeing today is the inevitable result of national leaders who have forgotten the fundamental wisdom of the Tenth Amendment [which provides for America's federalist system]. Just as Mr. Jefferson warned us, as soon as we as a country disregarded the fact that the federal government's powers are limited, and that we as states and individuals hold the balance of the power, the floodgates were opened to the torrent of federal power grabs we're seeing today. Take the federal income tax, for example. We tend to think there are two constants in life: death and taxes. But America hasn't always had an income tax. The first federal income tax on individuals was imposed in 1861 to help pay for the Civil War. But the tax was never meant to be permanent, and Congress repealed it ten years after it was enacted. It wasn't until 1913 that the Sixteenth Amendment to the Constitution was ratified and the individual federal income tax that we know today was created.
What is most dangerous about these power grabs is that they're usually done in the name of a good cause--insuring the uninsured, for example--and have a big wad of cash attached to them.
