Money buys a happiness only poor people understand.
Where I come from, EVERY poor person understands that whatever pain you have - hunger pains, being outside in winter, being thirsty, being ill, etc., can be solved through money and not having money means no solution for the issue. Poor people generally accept that money doesn't give you "genuine perfect joy" but this is an exaggeration. It gives you a different joy, called "Security". This is based on Abraham Maslow's Hierarchy of Needs; in short, the first needs you have are your immediate security needs and money is the current world solution for those needs. When you've got your bills paid, and you aren't worrying that buying food today might mean my car runs out of gas on the way home from work and then I am screwed...
