Women choosing was the worst thing to happen.
It was technology and female abundance that exposed the shortfalls of women choosing. Women didn't have abundance until technology started playing a part in mating.
Need to return to arranged marriages and a society that shames women for being promiscious. Not saying we didn't have cheating during an all time high of marriages and LTR. But it was far more secretive and lower in percentage. Women were not made to be the deciders in sex.
In the United States, arranged marriage was never a major societal factor.
There was once more shame for sexual promiscuity in the United States. The Sexual Revolution of the 1960s-1970s started it, but even into the 1980s women kept lower body counts than post 1990 (see table below). Those data points are reliable indicators because most Western women are still marrying, but there are more people who never end up marrying than in the past. In 1990 or 1995, it would have been extremely odd for a woman to reach her 40th birthday and have never married.
Women have been the gatekeepers to sex in the United States since before the Sexual Revolution of the 1960s-1970s.
Fewer devout religion practitioners has also increased promiscuity in the USA. Religion's role in a culture is a factor in the shame surrounding promiscuity.
