I have a few people in my closer circle that do the online dating thing. Watching what they go through, I'd rather be shot or stabbed again.
One of the problems is that with the breakdown of the family structure in the country, and with people not going to church anymore, the last places left to meet people are work and school. Getting into romantic entanglements at work is a minefield at best. I always scream at people to not date coworkers. So, what is left? People don't have money to go to places any more, and clubs are not a place to go for dating. People are told to get into a hobby, but the issue with that is men and women tend to be into different things leading to segregated lifestyle choices. Nobody really wants to be hit on at the grocery store. Or at a department store. Or getting their overpriced coffee in the morning.
The short of it is that if you do not get hooked up with a life-long partner in school, or when you are young, you are going to have issues later in life wondering where all the single people are and how to make friends as an adult.
I've joked before that we need to go back to arranged marriages. That just presents a different misery. I wish I had an answer here.
