Jeans are the weirdest default style, a throwback to when they were a symbol of the US's cultural domination. They're often designed to project an image of hard work and use that very few of us do today. They are one of the few pieces of clothing that we intentionally buy pre-damaged with fades, rips, and holes since it skips over the actual hard work we would need to do to achieve those fades, rips, and holes.

In modern times, there are better options than jeans for almost all work tasks, and modern jeans are usually not designed for work as they're cut too slim and made with spandex. Jeans are basically a costume.
