The study is titled Mismatches in the Marriage Market by Lichter, Price, and Swigert.

Lichter, Price, and Swigert (2019) stated that there is a lack of “economically-attractive" men which is just a scientific way of saying that there is not enough men who make enough money for women to be attracted to. The funny thing (or very sad depending on your point of view) is that these unmarried women made less money than unmarried men!

Yes, the year may be 2020, but men are still expected to be the primary providers, even when that is an entirely unreasonable and illogical expectation. And it's likely going to get worse, not better. If women did somehow close the income gap their unreasonable expectations would only increase, adding further to the gross imbalance the mating market.

Unmarried women only make an average of $29,250 per year but are unwilling to marry an unmarried man who makes an average of $31,366 per year (Lichter, Price, & Swigert, 2019). Clearly someone who makes a few thousand dollars more is not “economically-attractive."

These unmarried women want a man who makes an average of $52,020 per year. In other words, the average unmarried women wants a man who makes ($52,020/$29,250 = ~1.7784) 178% of their income.
