Do they give out enough Founders' Awards to make their base salaries irrelevant to people who would otherwise be launching successful products at a smaller company? This seems like a highly speculative question. What percentage of potential employees that would have begun a startup would be "successful"? How do you even quantify this? What's different about "working for Google compared to a startup" versus working for any other company rather than being your own boss? Why do you ask about Google only?
