The basic services that keep us alive (e.g. farmers producing our food) tend to also be "easy" (it is physically demanding, but doesn't require years of study to start and you quickly learn by doing). This also means that the vast majority of people would be able to do this kind of jobs. Our economy pays more for scarcity, i.e. jobs that are in demand and at the same time require more qualification, so that the number of people needed in that position tends to be less than the current amount. Both views have sense, they just start from two different points.
