Uhm, no.
If ipads weren't made in China, they would be prohibitively expensive. Example? The 30%+ premium on American-made cars. Imagine, now, the extra expense on everything that goes in to building an ipad: the fabs to spin the ICs, the shops that assemble the boards, the panel fabrication units...etc, etc. AMD tried to build a fab in New York. Even despite huge tax breaks from the state, it still wasn't possible to open it...they had to sell it off. Without access to companies like Chartered and TSMC, we wouldn't have half the little gadgets we have, because they simply wouldn't be financially viable. And that's not even taking in to account the raw materials...most of which simply aren't available in sufficient quantities in the US.
Aside from that, protective tariffs would price us out of foreign markets. Tell me, how do you make an economy grow without access to external markets? That's why isolationism doesn't work.
You want to force American companies to use American labor. Tell me, how does that work? How does the iPhone compete in foreign markets against an HTC phone at a third the price? You may not have noticed, but in comparison to cheaper phones, the iPhone's foreign sales are aren't great:

Or, maybe you just want to make it so that products sold by foreign companies in the US are prohibitively expensive. How does that help anyone? All that does is make EVERYTHING more expensive. And now that we're no longer exporting anything, because everything we make is more expensive and foreign countries will have enacted reactive tariffs, our wealth stagnates...buying power never goes up, and we're worse off than we were before.
The liberal's idea of free trade (what we have with NAFTA and China) doesn't work. There need to be tariffs. But, you CANNOT force companies to use American labor. That is not the answer and does not address the issue. Americans need to change their entitlement way of thinking before domestic manufacturing will be universally viable for all products. They don't need to be competitive with Chinese wages...they need to be competitive with Chinese wages + the cost of the logistics of getting product to and from China, which isn't cheap.
I'd love to see more domestic manufacturing, but, frankly, American's don't deserve the jobs. They're all a bunch of whiney, entitlement-minded fucktards.
