Any sufficiently large corporation cannot continuously hire smart people since there is a tendency to push for the average. Google has avoided this by applying something known as the "Lake Wobegon strategy" (http://googleresearch.blogspot.com/2006/03/hiring-lake-wobegon-strategy.html). It states that a company should only hire candidates who are above the mean of the current flock of employees.
Though, as I stated earlier, even Google cannot continue to endlessly hire smart individuals. A sample of the average IQ of University students would most likely be the same as the rest of the population. There are always a few exceptional individuals in any group, but the group itself is most often average.
