You can passively earn money in the game. Just get enough stars to unlock these skills under BRAND. You'll earn a total of $1900 per minute, or $114,000 per hour. You can literally go AFK or do other things IRL and as long as you don't close the game you'll be earning more money than you'll know what to do with. Just be sure to save your game every now and then so you don't lose progress in case you accidentally close it or something goes wrong.
