A couple of things here
1. The state has ruined marriage. How? They have given certain legal perks to being married, which is why you have playboy bunnies marrying 90 year old men. Marriage has become a financial decision in many respects. The Left says they want the state out of the bedroom but that is a big lie. They have no problem having the state discriminate against polygamists, for example. But sadly, marriage is big business for lawyers and the state. You have to pay for a marriage license. Why? What did you do to earn the license? And the lawyer profession makes a killing from it.
Now if you got the state out of the marriage business, what would happen is only religious folk or people serious about marriage wanting to get married, and the divorce rate would plummet. Remove any financial incentives for divorce, and it will fall dramatically.
For example, if you do research regarding Christians who get a divorce, you will see that it is just the same as the rest of the country. However, if you do the same search on couples who attend church together every week then the divorce rate gets chopped in half.
In other words, the success of marriage depends on your devotion to it and love for it. It's hard, but most American like the easy button and don't want to work at anything, like going to church every week.
2. Society is more self absorbed. Community is virtually gone. Marriage demands sacrifice, sacrifice for those you love. Most are not willing to do that, especially those who are wealthy.
Just look at Hollywood. All of these people only are about themselves and their career. Therefore, any long lasting relationship is almost impossible. Once the married party becomes and eye sore or annoyance, off they go and on to the next.
Again, money is valued far more today than family. And as we see kids shooting up schools and the drug epidemic exploding, etc., it's no wonder.
Wow, we've all heard of the price of gold these days? Dave's size 10 14-karat gold band...$699.00.
