I work with a man named Darwin. He is a 23 year old Mexican man and speaks very little English. Every morning he wakes up at 5:30 AM to go and work at McDonald's at 6. He works there until noon and then goes to work at Wendy's until midnight. He never takes any breaks and he works seven days a week. He doesn't have enough time to sleep properly let alone do anything else and he still hardly makes ends meet. 

Many of my colleges are in the same position as Darwin. They work inhuman hours just to be able to barely survive. They work hard hoping that there children will study hard and make something out of themselves.
