The chart above shows market capitalization trends for Apple and Microsoft over just two months in 2010.
To show that this trend of Microsoft's failing hegemony is not a fluke, here is another showing operating income from devices running Apple and Microsoft systems from 2007 to 2011(click either to enlarge).
Microsoft's in-house response to its own leadership failure and loss of market share has been to double the percentage of its employees in the lowest rung of company performers (from 10 to 20 percent), cut in half the percentage of top performers (from 20 to 10 percent), and to tie these salaries to their performance levels. In short, punish the workers for the failure of leadership in the company to do anything other than produce crap products.
How does that [KIPP school] compare to a normal school? Well, in a normal school teachers aren’t told how good they are. The data isn’t gathered. In the teacher’s contract, it will limit the number of times the principal can come into the classroom—sometimes to once per year. And they need advanced [sic] notice to do that. So imagine running a factory where you’ve got these workers, some of them just making crap, and the management is told, “Hey, you can only come down here once a year, but you need to let us know, because we might actually fool you, and try to do a good job in that one brief moment.
