Millions of single women in America today cannot for the life of them find a “suitable” husband.

That’s according to a new study from researchers at Cornell University, who examined data on recent marriages and found women’s ideal husband has an average income about 58% higher than the actual unmarried men currently available to single women. These optimal husbands were also 30% more likely to be employed than real single men and 19% more likely to have a college degree.
