Where will America be in 20 years?

Something that people overlook a lot as we go through our everyday life is how will things be different in the future. Things have change a lot in my lifetime alone. When I was born almost 17 years ago now computers were just being invented and people were not even dreamin about having something more powerful than the computer. Well now my iPhone is more technologically advanced then those computers. I can do things like write a blog from my phone and post it onto the Internet. 17 years ago most people didn't even have the Internet on their home computers. In 20 years America will look completely different if you ask me. China and other rising powers have control too much of the manufacturing done in the world and will eventually realize that they can cut off counties like the USA from simple nesecities. UnlessAmerica begins to make some of their own things we will be screwed. Also, how many states will we have? 50? 49 maybe? Will states secede or will we add places like Puerto Rico or Mexico? I feel like America is going to be very different within my lifetime.
