I mean, to some extent, there's absolutely causation. Lower pay means you may not be able to afford a car. If the public transport in your area is lousy, you'll be late more often. Lower pay means if you can afford a car, it's more likely to be an old beater, and if it breaks down, and you're not 110% prepared to switch to public transport on a moment's notice, you'll be late or miss work. Lower pay means a worse living situation. You're more likely to be in an old building, with a crappy landlord, who may not care about the asbestos in the ceiling, or the black mold in the walls, or the bedbugs, and then you're more likely to get sick. Lower pay means you can't afford good food, which means you're more likely to get sick. Lower pay means you can't afford regular doctor visits (especially since you're also much less likely to have any sick time—paid or not—in which to go to those visits), which means you're more likely to get sick. Lower pay makes it much more likely that you're in a high-stress job—one where you're expected to jump for superiors and customers at a moment's notice, and be punished for trying to act like a human being—which means you're more likely to get sick. Lower pay means you're more likely to be working multiple jobs, and thus getting too little sleep. That makes it more likely that you'll oversleep sometimes and miss your alarm, and be late or miss work. I daresay I could go on...
