No one's getting married these days!!! Why?

Coming from a home where my parent's have been married for 34years, it has always seemed natural to settle down, fall in love, get married, have children and live happily ever after.
However, in today's society, people have baby's without getting married or even putting a title on the relationship. I know sometimes mistakes do happen and some things pop up unexpectedly, but in Hollywood, it's like the it thing to do.... just have a baby... no ring needed... no happy home. Are people so scared of divorces that they rather not risk it, or are we coming to a new age where marriage is no longer a respectable union between loving couples?
