My take is that the world is a massive place with countless atrocities and bad things happening. It is impossible for a single human to actually "care" for all these issues besides sweet nothings "thoughts and prayers" and maybe a donation of a 100$.

Instead, I orient myself to my local circle, strata, whatever you want to call it to something I can care for and manage. I recently funded a few tickets for my local highschool for a science trip for instance. I give money to a local shelter I like to stop by and say hey to. I do a lot of things for a circle I've deemed mine to care about.

So it sounds mean or rude not to care, but it's what everyone is doing. No one just wants to admit it. Champion a few causes that you can handle and let your taxes take care of what you can't.
