This is quite distressing, showing how our quality of life has actually regressed by some metrics rather than improved as is normally assumed. Americans of the 1960s did not have to worry about Chagas, Malaria, or Bed Bugs. These were parasites that had been eradicated. It even seemed possible then that TB, a scourge on humanity for centuries, might soon, at least in the US, meet a similar fate. Now it, like the parasites, has come back full force.

Though neither the author nor the posters here will identify the culprit, I think it should be obvious to all but the most deluded progressive that this is a consequence of unchecked mass immigration to the US--a consequence I doubt economists factor into their models when trying to justify conclusions about its benefits.
