Not going to happen. Simply impossible. Manufacturing is way too spread all over the world. Besides "Made in USA" doesn't imply higher quality. Stuff made in Germany, France, Canada, Italy, Japan, etc., is equally good or better. And if we moved all manufacturing back to USA there is a chance we'll be making lots of junk too.

Besides, how do you know you're actually supporting American? Maybe the factory and workers are American but the owner is chilling in Taiwan or Germany. Do you know how many "American" brands are owned by Europeans and Asians these days? Chrysler, an icon of American engineering, is controlled by Fiat now.

Then there is the large picture: OK, so that Intel CPU may be made in USA, but try to find good motherboards, memory and hard drives made in USA? What are you going to do? Frame that CPU and hang it on your wall or build a computer?
