South African job listing site JobVine compiled the following chart of the top ten salaries at Google, compiled from Glassdoor.The top pay is for contract positions leading software development. It's not uncommon to see contractors earn more salary than full-time employees at big tech companies, because they're often not able to get stock options and perks.For jobs within the company, it looks like directors of product management are the highest paid, which is fitting with Google's new emphasis under Larry Page on product over engineering.Image: Jobvine.za via Glassdoo...

I'm not an economist by training, but I've spent a long time observing markets, and I've often wondered what the great economic thinkers of centuries past (Marx, Smith, Keynes, others) would say if they were alive today and could witness the transformations that have been caused by mass media (radio, TV, print) and the Internet. The Internet, in particular, has had a transformative effect that will doubtless be studied for hundreds of years to come.One of the things that can be said about pre-Internet markets is that most markets permit the emergence of two or three major winners (a primary wi...
