Visiting César (sort of - kid's in isolation, but his follow-up exam, post-surgery on Sunday, shows 50% reduction in infection thanks to stem cell therapy; I'm delivering supplies via his nearest metro station).
This is a shot of the barrio right next to his. These are Estrato 2 homes - the second lowest level, most made by hand with... very little regulatory oversight. Class labelling impacts taxes, so the highest (4,5,6) pay for gradual improvements in the rest.
Our world has such a range.
