The idea has a little merit. International soccer competitions are:
Summer Olympics (2020, 2024, 2028)
Men's World Cup (2022, 2026, 2030)
Women's World Cup (2019, 2023, 2027)
At the professional level, Women's soccer is not profitable both here and abroad. It will likely never be profitable.
At the International Competition level, its profitable because advertisers are looking to simply associate their brand with women's sport (P&G) and get much better bang for their buck. From purely a business standpoint, if international competition was held every two years, we could reduce the need to rely on the unprofitable element and push friendlies and regional competition, thereby putting the money where it matters.
