OP says:

Scholarships and financial aid are available in some circumstances. So if you're interested in attending, definitely apply, and mention you'd like to be considered for this. We'll set up a call to discuss.

Data point: me and my girlfriend did get a scholarship last year. (But if we were literally hungry students, even that probably would not be enough.) For us, the most expensive thing was actually travelling to USA. So for people like us it would be most helpful if CFAR could expand to other continents. But I completely understand that this is not the top priority of CFAR today. It could be a higher priority for people living far from the Bay Area. So if your situation is similar, starting a rationalist group in your community could be helpful. Just show people around you LW and HPMoR and see what happens. I hope that within a year or two it will be possible to have a CFAR (or CFAR-like) workshop in Europe too.

PS: I know some people value their internet anonymity, but if you disclose where you live, you increase your chances of meeting other rationalists personally, which is a great experience. With a small group, you could already start doing some rationality exercises described on LW.
