- Assuming that Doubleclick was the largest company Google has acquired
- Assuming that Doubleclick had 5,000 employees (generous estimate, I believe) at the time of acquisition
- Assuming that Google has only acquired the 75 companies listed in Wikipedia for Google acquisitions
- Using August 2008's census data
No more (and likely SIGNIFICANTLY less) than 375,000 people have been acquired by Google,
There are 154.9 million people in the American workforce (collecting salaries).
The actual number (based on the above information) leads us to believe that 99.998% of people make more money collecting a salary than they do being bought by Google.
It's worth noting, perhaps, that I might be counting the wealthiest 2% of Americans within the 154.9 million census number (or that there are dramatically fewer employees in the workforce since the bubble burst), but those wealthy folks were almost certainly not acquired by Google (although, if they were, it doesn't skew the numbers that significantly.)
