Yeah, I was just thinking something similar. "Rich means someone who earns more than me". As someone pointed out, even earning $50K a year puts you in the top 1% globally and arguments about "it's all relative" aside, I think most people are a bit more attached to their income than they think "rich" people should be.

I think the sad truth is that a lot of us don't necessarily believe deep-down that us forgoing, say, 10% of our potential income will actually be an investment into the world but will simply be sucked up somewhere else. That's why I like schemes like micro-investment where you can see that your money is genuinely invested in making the world better.
