I'd even say that payroll software could be a lot more interesting than many other fields. If done right, it shouldn't just be a boring tool that adds some numbers - it should educate its user about the current legislation (e.g. about employee status, tax optimisation), be useful for hiring and budgeting decisions, integrate with banking and accounting software,... I bet tax software isn't too bad, either. And at the end of the day, the dev hasn't leeched time and money away from some kids, but helped to make a real problem easier instead.
