That's a critical question that isn't being asked enough.
Americans aren't allowed to compete like that; there are too many labor and environmental protections in place to experience "Chinese working conditions" even if they wanted to. We legally can't work Chinese hours or affect the environment like the Chinese.
So while it's true that Americans aren't really willing to work hard enough to compete on price with the Chinese, it's also literally impossible.
And many outsourced jobs are like this. Americans can't compete because it's illegal to compete. Our hands are tied. We can't bend the local laws to make life cheaper for ourselves, and most of our products are sold to us by people who can and do.
I would be curious what would happen if in order to sell to American workers, you had to meet American environmental and labor conditions. I think that's a total non-starter, but it's a hypothetical that may cause the ponderer to address the huge gap in how competitive other countries are allowed to be to sell to Americans, vs. how Americans aren't really allowed to compete with them.
