It's a good tool for giving people a look at things through a poorer perspective. It really demonstrates the short/long term dichotomy.
I don't have too much money, and a while ago, I had to make a decision. I need my car for school, and my job is as a driver, so it depends on it. The car was making bad noises, had a damaged exhaust, and I was risking a citation by the police by having it damaged, and it caused the car to run poorly, costing me in fuel and potentially breaking down in future. I could pay the $300 to fix it then, or leave it and save the money. I ended up having to fix it, and cut the budjet for two months. You really end up sacrificing long-term health just to survive, the game reminded me of my diet of beans and noodles. The student diet isn't a health lifestyle, and while it's cheap, you'll pay heavier fees in medical expenses down the line if you're not careful.
I think the game needs to try to stop people "playing" the system. Try to make them aware of the shitty life they're living, and the overall decline in their happyness, health, and increase in stress, and family disfunction. Granted, I lost out on day 23, so maybe I missed that.
