Steve Job's salary was $1, this was widely reported.

Bragging about having a $1 salary is basically telling your employees that you make so much more in other benefits that you can choose to forego the one thing (salary) that makes up the vast majority of their total comp.

In Steve Jobs' case, it was meant to instill confidence that he was in it for the long term - at the time, Apple was on death's doorstep.

He also had enough cash in the bank prior to re-joining that he didn't really need the money.

Didn't he also get the use of a private jet or something like that? That might be considered part of his compensation and so take him above minimum wage.

Yes, any private use of company property will require tax reporting and he would have to pay income tax on that jet usage of at least cost.
