if someone's job title is the only reason you are not interested

If by "job title" you are referring to the job they hold, yes, it's perfectly valid and not shallow in the least to reject dating (or marrying) someone based on the fact that they are perfectly content working their entire lives as a 7-11 employee.

Also, if you marry someone who makes less than you, you aren't 'subsidizing' them, you are entering a partnership with them. You're view of marriage is also rather depressing and money-focused.

Once again, ignoring that as the insult it was obviously intended to be (why do you insist upon making it personal and taking pot shots?), that's a realistic view of marriage. Finances are the leading cause of stress in a relationship. If you decide to marry someone who is incapable of contributing to your marriage on an equal basis, you're always going to be responsible financially for the lion's share of everything. If you don't take that into account, then that's - yet again - a recipe for disaster.

I can't help but think that if this were an article about us men not wanting to "marry down" that most of the replies would be supportive.
