Flatteners 4, 5, and 6

Flattener 4:
in this flattener, Friedman mainly talks about the uploading option, which is the opposite of downloading. how this works is simple; we can just transfer or copy a file from the device we have to the network. He also considered blogs as flatteners because of their ability to make people communicate easily and express their ideas.

Outsourcing is the other flattener about which Friedman talks. It basically means taking everyday's job and paying for another company in another country to do it instead. Some companies have showed up offering this kind of services, such as accounting. Let's take another example of this; teaching through the Internet have been widely popular because it is easier, faster, and someone can do it while s/he is home. 

Flattener 6:

"Outshoring" is what a company devotes another company to do. They do that for many reasons, on of which is the fact of finding cheaper labor in the other country. For instance, what all people know is that China is the cheapest manufacturer nowadays. That is why we see some other countries have started to ask for less amount of money for labor work to compete with China. The US, as Friedman thinks, will face a problem related to the high paid doctors and lawyers. So, the US will not have the opportunity to compete with China. The US is falling behind of the education system, and less than China and other Asian countries. This will become an issue as long as the US don't solve it as soon as possible.
