How do you make a million dollars?

One reason I felt ok about cheating with the vaults was that it is so pointless to go up to a million. I think 500K would have been more than enough to make a challenging scenario. Even 250K would be a good goal. Now these three ladies have so much money it is ridiculous. I don't know what to do with them. I am considering moving the girls out and starting them as spell casters, since I haven't played that yet. If I do I'll need to decide where to put them. I'm also considering beginning the millionaire scenario again - silly as it sounds, I liked having that goal. Maybe I'll do that with someone else, while my kids (Nikita, Cassandra, and Blair, my new boysim) become wizards!
