Why do Leftists never understand simple economics when it comes to employment (or anything else)?
Businesses spend as little as they can in order to get the goods and services they need. This principle applies to lumber, raw materials, services, professional services, utilities, fuel, and so forth.
If you own a "professional" women's soccer team, you will pay whatever is necessary to field a competitive team. If they paid Minimum Wage, they would get a shitload of players willing to play, but the "best" players would opt out. So they increase it incrementally until they reach a level that captures the players they want.
The only time REVENUE is relevant is when the aggregate players salaries are too high for profitability with the aforementioned $51 million in revenue. But they are nowhere near that point now.
Bottom line: if these players think they can make more money elsewhere, they should go there, make the money, and STFU.
