Very true. And my opinion of why distribution becomes even more skewed in both the income and wealth, is that it becomes easier to exploit this small difference

Very true. And my opinion of why distribution becomes even more skewed in both the income and wealth, is that it becomes easier to exploit this small difference in skill thanks to computer and the Internet (and books are the best example: it costs nothing to "publish" the book in millions copies online, so the feedback loop moving slightly better authors on top works a lot better than in times of printed books).
