As the problems of poverty grow worse, a class of rabble (Pobel) is thus created.
I was stumbled across the above piece and when I read the Terry Pinkard's bolded sentence, I wondered if it were common in English language. So I searched on The New York Times to verify if there were other examples of the phrase "poverty grow worse". Before searching there, I expected to find a remarkable number of examples, but I found nothing. Thus I searched on the most important British newspapers, but, again, I found nothing.
This circumstace seems strange to me because the fact that poverty is growing is rather common nowadays.
However, apart further considerations, this question arise from the fact that the words "grow" and "worse", used togheter as above, sound strange and almost contradictory.
Can anybody explain and clarify if I'm imagining things or if I have observed an unusual way to write?
