Um, does this imply that if you aren't filthy rich, marriage is something about which you needn't be cautious?
I'd be cautious about marriage rich or not. Let's all take the concept of marriage seriously. Like it or not, it's a major factor in much of society. Jumping into it without forethought is about the stupidest thing anyone can do. It has a major impact not only on your life, but on the life of your spouse, your family, your potential children, your finances, your emotional health, blah blah blah blah.
So, yeah. If I were filthy rich, I'd be cautious about marriage. If I were dirt poor, I'd be cautious about marriage. There's only one situation in which I'd jump into marriage, and it involves BlueBalls, 2 litres of vodka, Petra, and a garden gnome.
