You might want to read up on how economists talk about supply/demand graphs. They have to offer me enough to make taking the job be better than my next best alternative (which might be sitting on my duff flaming on the Interwebs). If I have no skills and few opportunities, yes, that's going to be starvation wages. But the vast majority of people do have options so any employer has to out-bid the next best choice.
Without a minimum wage the floor drops out of your next-best-choices and large chunks of the population end up on starvation wages. This isn't a theoretical issue you need to estimate with graphs, it can be seen in practice in jurisdictions with extremely low or nonexistent minimum wages, or even in first-world gig work.
I do not believe that is the case. Standards of living consistently rose in England throughout the industrial revolution. I just read a book by Don Boudreaux and Phil Gramm which has an entire chapter documenting this.
That makes sense, you don't believe that's the case because you just voluntarily and uncritically filled your head with a warm load of grifty bullshit "documented" by a couple of right-wing lobbyists. If you'd ever read a real history book focusing on workers' standards of living in that period, the way that the propaganda book you hopefully didn't pay for flew in the face of it would've set off some alarm bells. Here's something to get you started: https://www.crei.cat/wp-conten...
Did you live through the '70s? I did. Life is immeasurably better now for everyone but the homeless guy on the corner. The wage stagnation myth is just that created by twisting statistics (e.g. ignoring transfer payments).
Look at the median home price vs. median salary in the '70s vs. now and the homeless guy might look like the only person who hasn't been totally hosed. It's the same for education costs, two things conveniently left out of inflation measures. Accounting for transfer payments doesn't change the picture either:

Tell me about it. I got laid off from my cushy high-tech job and spent 13 months trying to land a new gig. I lost count of how many applications and interviews I went through. High tech and software job markets are in a world of hurt right now.
So you know, and at the same time think that most anyone who wants a job has one right now? How does that work?
I have no doubt working in a Nigerian nickel mine sucks ass. But just like other sweatshops going back to the aforementioned dark satanic mills, you have to ask, why are people working there? Because it beats the alternative. The long term answer is to make Nigeria and Haiti (to pick two examples) more productive so they generate wealth, not make hiring people so expensive the employers all leave. And that's my point: yes some regulation can help some people in the short run. If it makes hiring people too expensive relative to their output, the jobs will leave and everyone left behind will be worse off.
People were often forced into the earliest mills because the (once popular) alternative, farming the commons and telling business owners to fuck off with their hellhole factories, was conveniently taken away. The alternative that people are choosing work over is usually not a lower-paying job but the threat of homelessness and starvation often worsened by the very business interests they're forced to work for.
Productivity alone won't do anything for workers, both the industrial revolution and the last half-century in the first world are proof of that. If you're worried about employers leaving for cheaper labor costs, good luck competing with every Chinese political prisoner.
