What a strange comparison. The choice is not saving 'wealthy white western life', all countries which are in the same boat are having to do roughly similar things. India in their lockdown weren't trying to save wealthy white western lives.
It also isn't about some theoretical saving of lives. Currently, across the whole of London, we are really struggling for ICU beds. A lot of places are cancelling elective surgeries again and I imagine this will continue. We're going to be making VERY difficult decisions about who can go to the intensive care unit soon, if some hospitals aren't already. Especially if god forbid you fall unwell with something needing the ICU, which isn't Covid related. Ambulances are taking absolutely ages to arrive at genuine emergencies. The system is swamped and that's with lockdowns. And it isn't just the NHS before someone pipes in with an ideological point. France, Belgium, USA, take your pick of other countries. With health systems which have been close to being overwhelmed or which essentially have.
People still seem to think these measures are put in place to protect 90 year old Doris or Francine or Juana, even though they've got only a few months to live.
