Outsourcing jobs to cheaper areas does create cheaper goods for us. This f**ks American workers though, but benefits American consumers. So goods, internationally, go down in price. So with no jobs, Americans have a hard time buying stuff, but with such cheap prices, they can essentially slightly more afford what they can't afford.
When the outsourced places start demanding more, then the corporation outsources again. This potentially leaves economic ruin everywhere: a world of ghost towns. Who can afford these cheap goods? If ghost towns are being created everywhere, who buys the product? Who benefits from this ?---Is it corporation owners? Capitalistically, they just invest more money in more businesses, though. So essentially, by saving money, they are creating more jobs.
But if history shows us anything, these jobs will just be put in areas with, realitistically, slave-labor-wages.
Second
Now, ecolo-economically, can we maintain our current lifestyle (maybe even the 1970s lifestyle, for argument's sake, as no one in their right forking mind could say that 2007 can be sustainable)? Does our lifestyle necessitate growth? Assuming we dont have economic growth (as economic growth is definitionally unsustainable), what lifestyle level can we maintain?
Ultimately my question is 4-part:
1) Is this economically-good for the long-term American economy?
2) Is this economically-good for the future ghost towns?
3) Is this ethically good for anyone?
4) What will we lose once we hit the right-wall of (progress and) scarcity?
I'm open for ALL perspectives. Sources would be appreciated, and synposes of sources even more appreciated
