Yet the US has the highest ratio of CEO pay to labor pay in the world. How much is paid to stock holders in dividends and how much is paid to labor? What percentage of expenses is labor vs, say, energy costs? These will vary by company and location, of course, but it's over simplified to the point of being wrong to simply say it's a global economy so wages are what they are.
Regardless of the causes, people are free to choose among multiple employers in the area they are willing and able to travel to, so there is also competition for workers domestically. If the wages are what they are and you can't attract workers, you will fold. People do not owe it to you to accept poverty wages to keep you in business, unless they are serfs.
Wages is a part of that competition for labor, often a large part, but not the only part. If you can't hire people, you're losing that competition. Your pay is not enough for your work conditions to attract available labor. It may be that you can't simultaneously win both competitions for labor and for market share and you'll fold, but that doesn't mean people won't work in factories. It means people won't want to work in YOUR factories due to the competition being more attractive. It's hard to get and retain quality candidates at the injection molding plant for $13/hr when temps at Ford start out at $17 with a shot at a union position, the Honda plant offers $21/hr, and Pepsi is union and $21-$25. Those are real numbers in my state, where the cost of living is pretty low compared to much of the nation. $25/hr is enough to start out on pretty reasonably. $13/hr much less so.
