I chose this photo from Pedro Meyer because in my perspective it shows the some highs and lows of society/economy, showing the add for caesars palace in las vegas and their luxury services they provided where people with disposable income can go visit, have fun and gamble etc. Then below the sign you see the struggle of field workers who are picking crops in the blazing sun, probably only making minimum wage or less and not complaining, just working. 
I like Pedro Meyer's use of black and white in some of his photos because it seems like it helps focus more on the objective of the photo.
