everything is primarily made in china. Even some things that are not necessarily labeled made in china, some of their components are made there, so they can be produced if china is cut out completely.
most manufacturing went over there because of tax cuts and profits. Not that things can't be made other places just that they will be more expensive and not as quickly produced. Chinese factories are very large, so they are fast... the shipping is what actually takes the longest in the process.
When it comes to good and services you only get to pick two of the following things: fast, good, or cheap. For most of our modern economy fast and cheap have been the choices, and china has totally stepped up to meet that need.
other manufactures can do the same things, just not as fast or as cheap. The quality is not always seen in the final product, like sometimes plastic is plastic- but definitely a difference in the quality of the way the work force is treated.
Though camel toe in women's jeans is almost exclusively a Chinese garment manufacturing quality control, in garment making. By adjusting the pattern slightly, they can make more pants out of the fabric, and save $$$ but the result is camel toe.
of course it's easier to just call the woman a slut and ratchet than than to address the manufacturing issue.
