WNT is the big club that needs the talent. And they do make money.A farm team for what? What big club needs that talent? A farm team produces talent that can be traded or sold for a profit. Farm teams don't have subsidies they have development costs that are paid by the club itself not an outside entity. Is there another league beyond NWSL that they get moved up to that actually makes money so USSL can recoup that cost? The athletes are paid what the market will bear they are not under paid. That is like saying the MLS is under paid compared to the Premier league. They are paid based on their leagues ability to bring in money and make a profit. If the league is successful the players in it make more.
USSF recoups the cost by selling WNT sponsorships, tickets, advertising rights, and jerseys.
If WNT starts losing, USSF sells a lot fewer jerseys. To them, it is worth an NSWL subsidy to make sure that doesn't happen.
Unless, of course, the current players succeed in getting most of the revenue. In that case, NWSL becomes a pure expense and there is no longer a reason to subsidize.
