A capitalist paradox is that all people with so-called unskilled jobs are not expected to cope with all qualified jobs. But a person with a skilled job is expected to be able to take all unskilled jobs as if unskilled jobs required no effort at all.
Another paradox is based on the false claim that unskilled jobs are unskilled. These are often very physically qualified. Heavy lifting. Craftsmanship. Speed. Cadaver discipline. With more demands for those who do the real physically heavy work. And the second paradox lies in the expectation from capitalist society that those who have not qualified for the so-called qualified jobs should be qualified enough to be able to take the jobs where you engage in society's real physically demanding jobs.
