Yes, and there are also people willing to work in unsafe conditions, work in illegal industries, and trade with the country's enemies. The "free market", as implemented almost anywhere, has never been synonymous with trading with whoever you want on whatever terms.
People definitely are willing to work below minimum wage; that's exactly why we need minimum wage!
It's certainly not a nice analytic function, but clearly the higher the minimum wage, the fewer jobs make economic sense.
If I could pay someone a couple of bucks a day to open and close my garage door, I could afford that. But the minimum wage is far beyond that, so I got an electric door opener instead.
If it allows more people to buy iPhones then most of the jobs created by that is made in China, which doesn't help local economy much.

Only a small part of the value of an iPhone is captured by China. Not much of it goes to the local economy either, but luxury electronics are also a small fraction of the economy.
Dining out, groceries, retail, housing, transportation, entertainment, travel, child care, home repair, cell phone repair, medical care etc... the local economy captures a large percentage of all of those.
