Earlier quoted context omitted.
China wasn't always that way: it was a choice they made to become the worlds manufacturers, with the complicity of the global financial elite. We moved the factories over there, we can move them back.
Why? After all the American people want cheaper things and that is done by moving factories to China.
Let's say that there's a $3.50 product that costs $1.50 to produce, and a company can save 10% of production costs by producing it in China (even with lower wages you don't tend to have huge savings when things like transportation, lower quality, distance from quality inspectors, etc. are added in). So that's a 15 cents saving - now some of that the company is going to keep (let's say 5 cents), some will go to the businesses buying wholesale (let's say another 5 cents), and some will go to the consumer (let's say the remaining 5 cents). So in the end it might be the difference between paying $3.45 and $3.50 for the consumer - something most people wouldn't notice.
Of course, for a company it's a much bigger difference - if everything costs them $2.25, and they're selling it for $2.75, then an extra 5 cents per unit means their profit margins go up 10%.
Of course this is going to vary a great deal depending on a number of factors (what kind of product, if you're buying generic, etc.). But I think for a lot of products the average American wouldn't notice much of a price difference if they were being made in the U.S.
