If it goes above 50K and stays above 50K, you're probably right. In my Bruti game, even having an entire family with zero management didn't stop me from passing the million mark, and couldn't keep me from turning a profit every single turn. It just reduced the vast amount of money I was making. But, a lot of times you can pass the 50K mark by scrimping for a few turns. That can wind up hurting you in the long run, by costing you management points from the extravagant/corruption vices that it brings so you make less money once you've spent that excess.
