The prize money from tournaments is so inconsequential to most men's players that a lot of them simply donate it charity or give it to their federations.

And actually as it's been pointed out elsewhere in this thread, the dudes are actually taking home a bigger piece of the pie than they did before. Previously, most of that money would just go into the pockets of US Soccer. So they're making more and also giving more to the women's team.

This is also not to mention that they'll also take home prize money if the women win as well, something that was not the case before.

The prize money here would make up something like 3% of Pulisic's yearly salary. I doubt he's feeling very "fleeced."
