There is the distinction that EBay sellers get most of the revenue; EBay just takes a cut and thus doesn't have to have a huge amount of revenue itself.

Doesn't this mean the company has to make more than $50 billion in revenue? Assuming a $50K wages a year, 1M jobs takes $50B to pay for.
Do the jobs have to be in the US?
Seems like an interesting idea, but my first thought is that you would want to find some way NOT to pay $50B a year... that would be a lot of profits. More profits than the vast majority of companies make.
It seems risky because it's hard to imagine getting to 1M jobs in less than 10 or 20 years. But in 10 or 20 years, computers will have gotten a lot better at the things that they are currently poor at. It's very hard to predict, but it will change rapidly.
Did EBay create 1M jobs? i.e. a significant number of people have made their entire living on Ebay. I think it might have been on the order of 1M, but not sure.

Ebay in 2005 claims 724K as primary or secondary source of income. If I had to guess it would be more like 72K "jobs", as 1/10th of those people might have Ebay as their primary source. That was 2005, but I don't think the order of magnitude has changed in the last 9 years.
