Well, that... and decreased infant/youth mortality, and increased population density, and increased pollution, and novel models of what qualifies "illness and problems", and social fragmentation, and cultural erosion, and de-institutionalization, and expansive communication, and sedentary lifestyles, and... well, and about a quite a lot other potentially contributing things.
