No, if you want money in the real world, you have to get a job. Final Fantasy VIII attempted to address this conundrum by making your character a professional mercenary working for a group called SeeD, which pays you a regular salary throughout the course of the game. Theoretically, this would keep your character's source of income a little more grounded in reality.

However, at one point in the game, SeeD's financial backer (a robe-wearing mole-thing called NORG) goes crazy and tries to kill you, leaving you no choice but to beat it mercilessly until it shrivels up into a cocoon and dies. This puts you in the unfavorable position of having just straight-up murdered the billionaire space muppet who paid your salary. There's no way you can continue to draw paychecks from SeeD when you've just slain the source of all their money.
But that's exactly what happens. Despite assassinating SeeD's primary benefactor and leaving the organization in financial shambles, you STILL get your money on time, without so much as a bounced check for the sake of dramatic tension. You even continue to get raises, which suggests a horrible oversight somewhere in the organization's performance evaluation department. Wandering through the forest hacking giant slime monsters with a sword until they turn into piles of money suddenly doesn't seem so kooky.
