A government big enough to give you everything you want, is a government big enough to take away everything that you have.
often attributed to Thomas Jefferson
Amongst monticello.org’s extensive listing of spurious Jeffersonian quotations they have a nice piece of sleuthery on how this quote’s purported provenance has changed over the decades of its rhetorical deployment:
Earliest known appearance in print: 1952 
Earliest known appearance in print, attributed to Jefferson: 2005
This particular saying seems to be getting a huge workout at the moment in anti-Obama commentary around the web, usually with the Jefferson misattribution. I expect there’s a fair bit of overuse in anti-Gillard rhetoric as well.
I’m always struck by how often the USA’s Founding Fathers get dragged into modern political debates, often with words that were never theirs in the first place.
