PS: By the way, there's a bit at the end where it sounds like the UK General Election was in 2008, though it was actually 2010. I really just meant things were starting to go Tory and weird around that time. E.g. that posh racist MP off Have I Got News For You? was suddenly London Mayor.
PPS: And an addendum to the bit about how economists construe "demand": maybe you can also think of payoffs within game theory and mechanism design as an alternative / complementary way in which economics tries to think through desire and satisfaction with a bit more nuance and granularity.
