GP was off by a factor of about ten, so the U.S. is instead around 30 times as rich. Source: http://en.wikipedia.org/wiki/Economy_of_Africa [wikipedia.org]

Africa is actually about a tenth as rich per capita as you just claimed it was. Source: http://en.wikipedia.org/wiki/Economy_of_Africa

It's a pain, but you have to go to the bottom of the page and click the "Check for New Comments" button until all comments are loaded, at least if there are over 250 comments (with my settings, which I'm unable to improve). It will only give you 250 new comments at a time, too, so if you want to load all of 501+ comments you need to click it multiple times, waiting in between each time.

FTFY.

That's not how you're supposed to use time in equations, unless you can substantiate the idea that the name of the year itself has a large impact on things. Instead the proper default is to set the beginning of your data points as having occurred at time unit 0.

Different ethics are not necessarily ignorance (or rather based on such). Your post is just an emotional appeal. In the end, the grandparent (aptly named with regards to this post) is only reflecting a view endemic (albeit usually not thought of in such a clear and thus easily derided way; a way that also would increase the difficulty of effective self delusion) to those with less time left to live than the amount of time their actions will take to begin affecting or will continue affecting the world (the full or extra damages after death are not automatically considered a debt for the person, unlike the damages the person will actually oneself experience). Old people have no fundamental reason to care about the future. Ponzi schemes for everyone!!! ;p

Anyway, just saying someone's ignorant (naturally while also not enlightening them, of course) is little different from just saying "You bad". It is not a logical counter in any sense. The GP is actually very correct. You can only care while you live. Once you cease to exist there is no way to care anyway. You having different ethics from for example a disbelief in altruism does not make otherwise truly wrong, as in logically inaccurate. Unfortunately almost everyone thinks like the GP to some extent, especially for people outside of each of their monkeyspheres, and the GP is simply embracing one way to avoid being buried by everyone else's selfishness: Simply be at least as selfish as the rest are (or at the least be very untrusting), or you have quite good odds of being damaged WITHOUT ending up with anything to show (i.e. enjoy) for it. Oh well.

This. Why pretend that the system is worth anything when it clearly isn't? Just because you want to believe the system could work doesn't make it so. Let what is broken die as fast as it possibly can...

All you need to understand are the "interpretations" of stuff the average believers (of whatever group you want to understand better) go along with, not all the stuff in the bible, internal contradictions, bigotry, and fantasy included.

Hurry everyone, to the perimeter defense!

I sell the photonic information my body and property reflects, but no one will pay me for it anymore now that there are more attractive sources of it from others!

Damn thieves! What is this world coming to?!

Here are my suggestions:

A megacity (10,000,000+ residents (1+ of which do not live in your household))
A metropolis (1,000,000+ residents (1+ of which do not live in your household))
A city (100,000+ residents (1+ of which do not live in your household))
A town (10,000+ residents (1+ of which do not live in your household))
A burg (1,000+ residents (1+ of which do not live in your household))
A village (100+ residents (1+ of which do not live in your household) and/or few stores or employers within 200 meters (656' 2"))
A hamlet (10+ residents (1+ of which do not live in your household) and/or very few stores or employers within 100 meters (328' 1"))
Rural (only your household and your household stores or employers within 50 meters (164' 0.5"))
McMurdo Ice Station (approximately 1,000 people in the summer and fewer than 200 people in the winter)

I voted for "An ordinary city", but I would live in "A town" under my suggestion. I specifically picked powers of ten for the population levels, so they may not agree with your preferences.

And 8-15 and more than 15 (although I prefer 16 or more)?

But CowboyNeal stole my mug!
