Why do people move?

"Why do people move? What makes them uproot and leave everything they've known for a great unknown beyond the horizon? Why climb this Mount Everest of formalities that makes you feel like a beggar? Why enter this jungle of foreigness where everything is new, strange and difficult?

The answer is the same the world over: people move in the hope of a better life."

Martel, Yann. The Life of Pi
