This is an anomoly of the US model of professional team sports, where the league is owned by the governing body and the teams are frachises, allocated players who remain employees of the Federation.
In Europe, the league is administered and open to teams by competition. Teams employ their players and pay whatever the market will bear.
In the case of the England national teams, the women are paid, whereas the men have to make a donation to charity in return for the privilige of representing their country.
