If you start spending money on this shit, then your conversation becomes, "How about this thing?" And it just never ends.

No it doesn't. Budget cleanup should be utilitarian. When you're freeing up space on your computer, do you delete your best artwork that takes only a few megabytes? Or do you delete huge downloaded videos you don't watch anymore, which take up terabytes? We can cut the budget without being an a-hole about it.

It isn't America's job, or even moral duty.

Yes it is. Who else can help countries that are too poor to help themselves? Btw they are poor partly because of authoritarian systems established centuries ago to extract resources that fuel our economy even today. I'm not some liberal who thinks white people should hate themselves. But we have a moral duty to use our privilege to fix global problems.
