I very much doubt that Claire Fox is an accelerationist.
At the end of the day life quality is a logistical issue above all else. Jeff Bezos is not going around the country buying up all the single family homes and hoarding all the doctors in the country for his knee injury. If you want better medicine you need to invent more efficient technology through the capital markets to serve people. If you want more homes you need to invent better home building techniques to cater to the masses. Thats how increased efficiency works and its why our lives generally get better with services and quality of live each decade. Thats not to say there are not tweaks and governing to be done to the capital markets (the govt is the conductor), but this is the general aspiration and trend.
