I really don't understand why they keep saying that. I would bet that in any major city living conditions are perfect to spread this disease.
Couple of groups I think are going to be problematic:
illegals .... they will want to avoid ‘authority’ and will hide their sick and dead (IMO). This is like many of the Africans do and it will definitely spread Ebola
‘ferals’ .... low infos. The type of people who will not listen to reason or facts & will take every opportunity and excuse to loot, rob, run amuck. I could see blocks of cities in quarantine and then all heck will really break loose when food becomes scarce or they feel ‘trapped’. Rev Al & Rev Jesse will claim it’s “racist” and white America is trying to kill blacks. Political correctness and a death toll as a result will ensue.
Libs/progs, etc. .... similar to gun control, law abiding citizens obey and the criminals end up with illegal guns anyway. There will be “overreach” and middle class, law abiding Americans will suffer. As is happening in Africa, the very rich leave the country or have the means to get away from the epidemic. The very poor and low info violate quarantine, run from authorities, and spread Ebola anyway. The law abiding will follow the rules and have their freedoms and liberties taken away and I’m not sure to what extent we’ll get them back. How much do you trust CDC (who IMO has already screwed this up saying we have nothing to worry about), DHS, TSA, all the other militarized gov’t agencies, militarized police ... and a treasonous you-know-what in the WH who is looking for any excuse to declare himself Emperor and do away with our Constitutional system of government.
