That's a different matter. That depends on how many there are of each career salary on each pay scale. The Fan compilation lists 109 different careers, so the odds against a particular career appearing are 108-1.

A quick look through the list shows 12 careers that can earn the highest, $690, and 12 the max out at $210. I didn't look at the other careers. It looks as though the highly paid salary paths are as common as the less well-paid paths, although since there are more of them, the lower-paid ones will come up more often.

DrDan: They have to have exactly the same career. likes/dislikes and preferences for kids don't come into it.
