Losers shouldn't complain about not "winning enough money". You lost, you shouldn't be winning anything. They should award you negative money on top of your ammo loss, and give that money to the MVP on the other team. Then you should have to watch that character sniffing your money and slapping you in the face with it.
Then your character should be forced to enter a vehicle with whoever killed you the most, and begin voluntarily acting like a prostitute. And you get to watch your money dropping as it happens, since you're paying them for the honor of pleasuring them.
Then you lose all ammo and your garage is wiped and you're put in Bad Sport with 30 more days on your timer, which shows up 00:00:00.
Then your Social Club and Xbox Live accounts are suspended, and your gamertag is permanently deleted and banned from use.
Then they come to your house at 2 in the morning, set your house on fire, and drag you out kicking and screaming through the flames and embers as your whole world is destroyed in front of you. They throw you into a van and show you the part of the ToS you agreed to that gives them full rights over you and all your property. Then they slap you across the face with that too.
And then everything else that happened before happens again, except in real life.
Maybe that would be enough to drive the point home: You are not supposed to lose. The goal is to win. Do that and earn money.
