I need a quote about how lawmakers can take away freedom without people noticing.?

A group in our area is trying to restrict the freedom of members by passing a law eliminating elections and restricting the rights of members. They say it's "in the interest of efficiency". I'm looking for a quote that will be included in a letter against this. Something about how people can lose freedom without noticing. Maybe something from Machiavelli? I'm researching, but I'd appreciate suggestions from all you erudite people out there! Thanks in advance!
