I agree, you can increase your chances, by bringing more to the table, than you have in the past. On the other hand, in an economy (which is being looted) where 2/3rds of full time workers earn less than 40k per year, it is unrealistic to think that everyone who tries hard, will get a job that can support a family. On the other hand, there are other ways to provide for a family, besides earning a bigger paycheck, than 2/3rds of the other working men do. That may not be good enough at a well to do trad chapel, but it should be at less well off chapels.
A girl who really wants a family and doesn't want to be pulled away from the home by sharing the provider role with her husband, may be willing to settle for a husband who wisely relies on family to provide his housing and utilities, because he only earns around the median wage in america: 25k per year.
An elderly relative, in particular, may be quite appreciative of having the company and help around the house. Of course, it could take a lot of patience and prudence, to live in a situation like that. Those attributes, fortunately, are available to all who will work for them. Of course, I am much more inclined to sloth, than I am to diligence and I don't think I am unique. Our culture, while spouting platitudes about hard work, seems to encourage sloth and discourage diligence.
