I'm new to EA, and my experience talking to people about it has been different than yours Gleb: They're very pragmatic, and ask an important question I don't have a good answer to.
Here's how my conversations usually go:
I explain EA/Peter Singer THEM..."yeah, but the ECONOMY! It would be bad for everyone because the world economy is driven by consumption. If we stop that it won't work." ME: "when people get richer, they have more money to spend to buy things, which provides a larger market for the first world, and thus could improve the world...
Thanks Gleb. Any suggestions for where else I could post/who else I could ask? I'm sure someone's got to have put some numbers together!
Thanks! Ryan
