Try Google.
I suggest you familiarize yourself with a company called “Foxconn”.
There should be a wealth of information about it!!!
For example, did you know that the largest iPhone production facility employs 400,000 employees?
Wow! That’s a big number, huh?
Let’s put it into perspective, shall we?
Obviously, a facility that size would need to kinda be in the middle of nowhere... we’re talking about the population of a city descending upon it on a daily basis.
But for nice round numbers.... let’s pretend it could be put smack dab in the middle of Los Angeles. That’s a big city, right?
I believe the Los Angeles population is about 4 million.
Easy math! =)
You just get one out of every ten people living in the city of LA to start working at Foxconn, & your idea (If I can even call it such) will work fine.
Hopefully your mind went “Wait... that would never work, I mean are there even that many unemployed? what’s the chances of literally every single one of them wanting to work there & appropriate candidates? Huh, maybe I should Google more. Wow, it seems like Foxconn, even in densely populated China has to run fleets of buses miles into other provinces even, to collect up a workforce that size. This doesn’t seem remotely feasible in America”.
Further... I don’t feign to know what you and any of your friends and family do for a living, but I would hazard a guess near zero of them have repetitive motion production laborer jobs.
The type of people that usually do that work here are high school drop outs and felons.... and they HATE their jobs. We’re taught in America that creativity & freedom in the workplace are hallmarks of success. Nobody here is going to proudly state at a dinner party “I put a single speaker in iPhone housings thousands of times a night”. That job would be performed here, begrudgingly, with heavy complaining, to the lowest acceptable rate, with very little pride in the work, because our society doesn’t value that type of work. Now, switch to China... the above proudly exclaimed statement may illicit comments like... “Really? How impressive & fastidious! Would you like to meet my daughter? She’s unmarried, you know...”.
Their ENTIRE SOCIETY is set up for this type of work to be of higher quality there!!!! Step outside your American bubble & try to fathom other cultures. It’ll reward you in many ways... having the business acumen to quite easily parse why iPhone production in America is near impossible is but one small benefit, sir!
