It's not necessarily to do with harder working alone - it's the stress from job insecurity. If you're an IT worker and lose your job, you can probably find a new one before your rent/mortgage is up. Worst case, you miss a payment or two or you have to cut down on nights out/coffee/whatever. If you're working something unskilled or where there's no shortage of workers? And you're living paycheque-to-paycheque in the first place? That's mentally distressing on a long-term scale, on top of requiring more physical work. It's not something that's ever going to get fixed - education is unaffordable even before you realise that your kids are going to starve while you're seeking it. CEOs do not do physical work most of their workday, by the way, so even if the point was solely about physical exhaustion your point would be moot. They are also broadly not worried about not being able to pay their bills. Basically - there's an intersection of issues which low-wage workers suffer from. Job insecurity causes many of them. The solution is to ensure that people don't feel like they're going to struggle to keep their living-place and pay their bills when they lose their job.
