This is really a confluence of both men’s and women’s issues, changes in some social roles, and differences in economic realities that social structures haven’t fully adapted to yet.
It’s a social reality that more women “marry up” than men. This holds in every culture I’m aware of, which makes me think it’s probably part of how human women behave. That means that this tendency can only be influenced by culture, not changed completely. In today’s world, more women are able and willing to go for higher education, they have better job prospects themselves, and they are socially conditioned to use a pretty stringent set of criteria for choosing a mate.
I’m not surprised at all that working class men in their 40s are finding it hard to find a woman to marry. First, there are few women in their social class who are available. Lower to lower-middle class people tend to marry earlier and are more likely to have more than one child. That means that even if they get divorced, they’re probably going to still be in their 30s and will probably have at least one, and perhaps two or three kids. Anybody in his age bracket is probably going to be remarried, anyone younger is already married or recently divorced, with kids.
Many bachelors are not willing to deal with her ex’s kids along with their own future offspring (another at least partially biologically-determined behavior) and quite a few of the guys we’re talking about wouldn’t be capable of supporting a family of great size, even given the child support and/or alimony she might be receiving from her first boyfriend or husband. Compounding this, a woman who has just gotten out of a relationship is probably looking for even more security than she had before, to make her feel safe and able to care for her children, so she’s going to want to look for someone better than her ex, even if this is an unrealistic expectation on her part. This might make her overlook an otherwise good prospect.
One of the traditional mating strategies — finding a woman who is much younger who is also looking for marriage — is now socially discouraged. Many people would consider a guy in his 40s looking for women in their early 20s to be predatory. Really, though, even in our present society, many women of all social classes want to get married by their mid-twenties. It’s not just that many men are looking at that age bracket (due to perceived sexual attractiveness, availability, or whatever) but that the women themselves go through stages where they value marriage more than autonomy, or that they are at a place in their lives where marriage requires less of a lifestyle change. By their early 30s, both men and women are more independent, more set in their ways, and may not really want a lot of change in their lives. That attitude has an impact on whether or not they consider marriage to be a good thing to do or not.
For all you single older guys out there, prospects are not completely bleak. There are women out there who are interested in knowing you. The trick is to find them. It’s one of those simple yet very difficult things. Dating advice doesn’t vary much. Internet dating is one prospect. Find something that you’re interested in and try to meet women who share your interests. This is a bit harder for bachelors since guy interests and girl interests rarely coincide, but it’s doable. Basically, find where the women are and find something to provide an in with them. Like Tuckerfan said, this article isn’t the authority on everything, and your situation may be completely different from those of the men in the article.
Don’t refuse to consider an international marriage. Mail-order bride or otherwise, sometimes the exotic and unknown factors can make you a better prospect than otherwise. I’ve seen quite a few guys in Japan with women who would probably be out of their league if it weren’t for gaijin power. Not all of them will get married, and not all of the marriages will work out (the failure rate for international marriages is a bit higher than the norm) but it provides some possibilities that might not otherwise exist.
Consider taking some language lessons in order to meet women who are in your country to learn your language. Some of them are undoubtedly looking for foreign husbands. Not necessarily for a green card, but just because they want better or different prospects from their home country. Believe me, all my bitching in other forums aside, Japan is a first-world country and Japanese women have no real economic incentive to marry outside Japan, but Western men are often seen as an attractive prospect even when the woman still has good odds of marrying a decent Japanese man. If she’s in her mid-thirties or older, is a bit “odd” by Japanese standards, or doesn’t come from the best family, she might be even more inclined to marry a gaijin. That’s just one country among many you might be able to work up an interest in.
