Would be interesting if sims had 2 separate money bars, the top one for the household, the bottom one for the sim.

The top one would calculate all of each sim separate money, while the bottom one would be what each sim made at work/selling stuff. Then if we got in Build & Buy and wanted to fulfill a wish buying something a particular sim on the household wants, we would have to mark that little circle in the sims personal money bar to use from its money, but if we wanted to buy something of common use, then we would have to mark the household money bar.
