The capitalist dream, sims' style.
Now, the sims can be their own bosses, and the architects of their own financial-fate. Possibilities are very broad, from lemmonade stands, to servo-industry, and from convenience-stores to financial empires... It only takes some assets and stock, a few management skills, and your very own troop of slaves... I mean... employees. to keep crazy low-prices or perform barbarian robberies, it is up to your sim.
All of this benefits can be yours for a long time, unless an elevator kills your sim (litterally). Good luck!!!
