What do you guys think about Marriage?

Families values is the very core of society, just look at families with no family values. 

you get high crime rate, bastard children and degenerates

It's not really mandatory. One shouldn't feel forced to get married just to please or contribute to secular society. We in general live in an evil world.

 I'll probably get married on my late twenties or early thirties

Marriage is the foundation of your family structure.  it is also the foundation of society as somebody has already mentioned.

You are committed to each other's needs for better or worse for the rest of your life. 

 men are not designed by God to be alone. Nothing good comes out from being alone.

We are social beings.
