A while ago the Economist pointed out that one of the Rothschilds died of an illness that would today be easily curable with antibiotics, but at that time the cure could not be bought at any price.
TB is "just" a bacterial infection. Today, in a wealthy industrialized country with universal healthcare, if I caught TB they'd "just" cure it here. Cures are possible, often even relatively easy.
But all three of the famous Bronte sisters probably died from it (TB == "consumption"), not far from where my mother lives today in that same industrialized country. And most years today it is still the leading cause of infectious disease deaths because even though we could cure it we just leave poor people to die instead.
No offense intended but The Economist is very low-quality.
*edited year of death
No offence intended but wavefunction is very low-quality.
I do not agree with their political views, but I can say the same about most papers. To a large degree this site is also beginning to be troublesome politically.
