It is happening worldwide, among all people and cultures. A rational response to loss of income is to delay marriage. Ways to reduce the crisis:

2. Encourage women to follow news of finance and economics better, and to focus on the bad news. Then they’ll worry that their husbands can’t support them, and will also want to put off marriage.
