But if Bill Gates wnted to empty the grocery store of other customers before he went shopping you would charge him more.

Facebook don't want Muni buses and Muni uus drivers, they want exclusive buses and that creates extra costs which they need to pay for. Here the extra costs come from exclusivity and split shifts.

I don't understand the relevance. They are not monopolizing muni busses and muni drivers. On the contrary, they are creating more venues (Bill Gates would pay someone to run his own private grocery in this awfully-stretched-and-no-longer-fitting analogy).

They are happy to pay for the extra costs - but not more than they need to. Now, the question is "how much do they need to pay for that" - and historically, this answer is reached by matching supply and demand subject to regulations.

The bus drivers might want to increase the price (by reducing supply - that is, in fact, a union's leverage). Facebook might counter by hiring a different bus company.

If the wage is not livable, they will not find drivers because those drivers need to eat. If the wage is livable and there are willing employees - why should they pay more? "Because they can" is an answer I personally find unacceptable.
