My argument is that raising the minimum is helpful, but it will be ultimately undermined when companies are just absolutely dead set against any consideration besides their own profit margins will find ways in order to compensate.
I'm not necessarily saying it's more profitable for companies to treat their employees like, you know, humans, but that there are in fact benefits for doing so. Unfortunately those benefits aren't $$$ on the financial report, but they are enough such that it's completely possible to create a successful business while still rewarding employees with more than you have to. See my examples about Costco and In-N-Out.
Given that, it should be possible to make it so that the national economy can survive without treating the majority of people as expendable means of labor. But the problem is that basically our entire market is acting like the airline industry. They established a new norm that put burdens on the customers/employees saying that it's necessary for things to be like this in order for companies to stay afloat, but in reality it's only necessary in order for them to make record profit margins.

It's not just an issue for unskilled labor btw. Studies have shown that there are many ways in which we can improve the way salaried workers are treated and that it actually increases productivity and employee happiness. For instance allowing employees to do 4x 10hr days rather than 5x 8hr days (thus giving them a weekday off to do tasks during business hours) is a boon, but many companies don't want to deal with having to create unique schedules or potentially not having an employee around on one specific day. Studies have also shown that requiring employees to stay to the end of the day everyday because they are being paid to be there, rather than their presence being dictated by task assignment and completion, doesn't net the company anything and can actually be counter-productive.

Other countries are able to maintain high wealth without working their employees to the ground. It's a uniquely American issue

Basically everyone else is approaching the way people thought America would go (towards 30~ hr averages), while America goes towards more work.

But just like when we went from 10hr days and 6 day workweeks to today's 8hr days and 5 day weeks, it requires people to stand up and fight for it. Unfortunately that doesn't happen when we have an entire group of people, most of which would benefit from expanded workers' rights, whose first reaction is to justify companies squeezing more profit. It's just like the people on Obamacare who voted for Trump; they are so concerned with making sure other people don't get something for free that they will have to pay for that they don't realize how the system is already exploiting them.
