I read it in highschool. Can't say it was my favourite, but I read a lot, and this is one of the ones that stuck with me.

Henry Kringle: Thank you for that thoughtful and well thought-out response, which got to the heart of my argument and addressed the issues that were raised.

Ditto what TwoShort said.

Also, perhaps it's also worthwhile considering the role that the US and other developed nations have had in making the rest of the world so terrible.

Part of the reason why many European nations are doing so well is that they spent centuries plundering the natural resources and labour of countries in the developing world. US prosperity is built on, among other things, slavery, genocide (or something damn close, in the case of Native Americans), a series of military interventions in states in South America and elsewhere, and a willingness to use their predominance in international affairs to push "free trade" policies that, arguably, make the lot of poor people worse.

It seems like the main argument for "border security" is: why should I have to give up my comfortable life? I don't want to!

I don't see how having the good luck to be born in a certain place, with a certain level of intelligence, into a certain family, &tc, makes you any more worthy or deserving.
