That's because of where those deaths are. I've seen 2 cases of active TB working in hospitals in the US in almost 20 years. Both from new immigrants. Sadly it's "mostly" a third world illness.
Unfortunately, nobody cares about third worlders. You can treat tuberculosis with antibiotics, which doesn't help if they have none or are too poor.
It's the same with refugees, hundreds drown in the sea and nobody cares, but if some billionaires disappear in a submarine on their way to titanic, millions are spent in an international collaboration trying to rescue their corpses.
It's cheap to treat TB. You are ignoring the fact that the medical systems in many of these countries do not pay enough doctors or buy enough medicine for their citizens. People die of malnutrition too. That's prevented by eating.
Are these "the capitalists" in the room with you right now? JFC dude, the capitalist countries you're complaining about are also the ones with the lowest TB mortality. Not everything bad is because of "the capitalists."
