many people think about it, but nobody lives in a hermetically-sealed reality on this planet. It might seem so, but the fact that the interdependence of everything and the results of ignoring it is starting to rear its head and stare us all in the face.
Homelessness is rapidly increasing and includes many seniors, like myself, and there are many factors in that that present problems for the rest of the population, like this article shows. When you have growing and active disease vectors, you increase the probabilities of epidemics and even mutations. Who is immune to the effects of that?
So, even if people who are homed and doing well in this economy don't care about the circumstances, affordable housing shortages and lack of services for those without, in a wealthy country with the resources, ignoring it won't make it go away and it very well could become a major threat to public health in general. That should raise more concerns and I don't think genocide is on the table in order to solve that.
Don't send for whom the bell tolls, it tolls for thee.
