Does money serve to bring people together or does it tend to seperate them?
There's 2 reason for this...
1, I wouldn't think money would bring people together. Unless your going to pay for a night out with someone or a group lunching or dinning.
2. In America, people who are married likely get divorces because of money. So it can be a BIG problem. If you want to look up "The most common causes for Divorces". They will give you alot of results on it.
