Raj Patel took the title of his new book from an Oscar Wilde quote:
"Nowadays, people know the price of everything and the value of nothing."
Wilde said that in 1891. Funny how while everything changes, somehow nothing changes...
Anyway, here's Patel talking about his book.
I haven't had the opportunity to read this yet (the local library doesn't yet have a copy, and I've been spending way too much money on books lately to buy a copy right now), but all the reviews I've heard and read have been positive.
