In the Past Dating Was a Fairly Simple Activity in the United

In the past dating was a fairly simple activity in the United States. If there was someone you wanted to go out with you would call them or ask them to go out for dinner and a movie. Nowadays it appears that many people are willing to pay large amounts of money to professional dating services to find a compatible mate. This idea is not a new one but it has increased quite dramatically in popularity. What does this suggest about what kind of good dating services might be and why? Are we likely to find this type of service be more or less prevalent in poorer countries?
