$2B divided by 600k employees would be more than $3000, which is actually huge for many people.
As another said, "color me unimpressed". He could double that and still be the richest man alive. He could triple that. He could quadruple that...
EDIT: For comparison, 50k USD is approximately 65k CAD, which makes higher than the median starting salary for a mechanical/electrical engineer in Canada. I would be surprised if they are paying their lowest-paid employees that much.
