I've always wondered why there's not a federal law requiring that the losing party of a suit is required to pay the winner's legal fees, up to an amount equal to what the losing party itself spent.

While you rarely, if ever, see cases where losing parties have to pay millions - I personally haven't seen any like that - you can see people having to pay tens to lower hundred thousand $ in legal fees.
That can be a substantial sum for regular people, and those circumstances happen when the other party has hired in high-$$$ lawyers, and the case goes on for a while. Especially if there's multiple appeals.
So there's always the risk of that.
If you want to sue a big company for treating you poorly, you risk a very high price of you lose.
