Crucial to understanding federalism in modern day America is the concept of mobility, or 'the ability to vote with your feet.' If you don't support the death penalty and citizens packing a pistol - don't come to Texas. If you don't like medicinal marijuana and gay marriage, don't move to California. Rick Perry
Birds have wings; they're free; they can fly where they want when they want. They have the kind of mobility many people envy. Roger Tory Peterson
Americans have so far put up with inequality because they felt they could change their status. They didn't mind others being rich, as long as they had a path to move up as well. The American Dream is all about social mobility in a sense - the idea that anyone can make it. Fareed Zakaria
The tax on capital gains directly affects investment decisions, the mobility and flow of risk capital... the ease or difficulty experienced by new ventures in obtaining capital, and thereby the strength and potential for growth in the economy. John F. Kennedy
There is a great demand everywhere in the world for individual mobility. People like the fact they are not on somebody else's schedule. They can come and go as they please. William Clay Ford, Jr.
